• Cataract Surgery

  Cataracts are a leading cause of blurry, dim, or glare-filled vision that can make reading, driving at night, and enjoying daily activities difficult. Cataract surgery replaces the cloudy natural lens with a clear artificial lens, restoring clarity and contrast. The outpatient procedure is safe and precise, and most patients notice sharper vision within days. Cornerstone Eye Associates is led by Claire Y. Chu, M.D., a board-certified ophthalmologist with a special interest in advanced technology cataract surgery. Dr. Chu has served as a clinical instructor at UT Southwestern Medical School for more than 15 years, received the Outstanding Service Award for resident education, and has been named to the D Magazine Best Doctors List in Dallas and Collin County as well as the Women of Influence list. Patients appreciate her thoughtful, research-informed approach and warm, respectful care. What Is Cataract Surgery During cataract surgery, the cloudy lens is removed through a tiny incision and replaced with a clear intraocular lens. The procedure typically takes only minutes, uses numbing drops with light sedation, and involves no stitches in most cases. Because it is one of the most commonly performed surgeries worldwide, cataract surgery is both safe and reliable. Vision usually improves quickly, and results are designed to be long lasting, allowing patients to return to the activities they enjoy with greater independence. Who Is a Candidate If cataracts affect your daily activities or your glasses are no longer helping, it may be time to consider surgery. Common signs include: Glare or halos from headlights or bright lights Blurry or hazy vision that does not improve with a new prescription Faded colors or a yellowish tint to vision Difficulty with night driving or reading fine print Frequent prescription changes that provide little relief A comprehensive eye exam can confirm whether a cataract is the cause of your vision changes. Advanced Lens Options Modern intraocular lenses can do more than clear the cataract. Options include toric lenses for astigmatism and multifocal or extended depth of focus lenses that can reduce the need for glasses at multiple distances. These lenses are designed to support active lifestyles and reduce dependence on corrective eyewear. Dr. Chu will discuss your hobbies, work demands, and visual goals, then recommend a lens strategy that fits your lifestyle and ensures your results are tailored to your unique needs.

• LASIK

  For many people, glasses and contact lenses are a daily hassle. From fogged-up lenses to the inconvenience of travel with contacts, corrective eyewear can limit both comfort and freedom. LASIK surgery offers an alternative by reshaping the cornea with a precise laser to correct nearsightedness, farsightedness, and astigmatism. The result is sharper, more natural vision without the constant need for glasses or contacts. At Cornerstone Eye Associates, LASIK patients benefit from the skill of Dr. Claire Y. Chu, a board-certified ophthalmologist who has spent her career refining surgical precision while maintaining a focus on compassionate, personalized care. With years of recognition on the D Magazine Best Doctors List and as a Woman of Influence, Dr. Chu is trusted by patients throughout the Dallas and Richardson communities to deliver vision correction with confidence and attention to detail. What Is LASIK Surgery LASIK, or laser-assisted in situ keratomileusis, uses advanced laser technology to gently reshape the cornea so that light is properly focused onto the retina. The procedure takes only minutes, is virtually painless with numbing drops, and most patients notice a dramatic improvement in vision within 24 hours. LASIK has one of the highest satisfaction rates of any elective surgery, with millions of people worldwide enjoying the freedom of clear vision. Because the treatment is customized, Dr. Chu carefully evaluates each eye to ensure the procedure is safe and well-suited to your vision needs. Who Is a Good Candidate for LASIK? Not everyone is an ideal candidate for LASIK, which is why a comprehensive evaluation is essential. Candidates should have a stable glasses or contact lens prescription, healthy corneas, and no significant eye disease. LASIK can correct a wide range of refractive errors, but some patients may benefit more from other procedures. Signs that you may be a good candidate include: Desire to reduce dependence on glasses or contact lenses Difficulty with active lifestyles due to corrective eyewear Stable vision prescription for at least one year Good overall eye health with no untreated conditions During your consultation, Dr. Chu will take precise measurements of your eyes and discuss whether LASIK or another vision correction option is the best fit.

• Photorefractive Keratectomy (PRK)

  For patients who want freedom from glasses or contact lenses but are not ideal candidates for LASIK, Photorefractive Keratectomy (PRK) can be an excellent alternative. PRK corrects nearsightedness, farsightedness, and astigmatism using laser technology, much like LASIK, but with a different approach to preparing the cornea. This makes it especially suitable for individuals with thin corneas or certain corneal surface irregularities. At Cornerstone Eye Associates, PRK is performed by Dr. Claire Y. Chu, a board-certified ophthalmologist recognized for her advanced surgical skill and dedication to patient-centered care. With over 15 years of teaching experience at UT Southwestern Medical School, publications in ophthalmic research, and recognition in D Magazine’s Best Doctors List, Dr. Chu provides patients with reliable, personalized solutions for lasting vision correction. What Is PRK Surgery? PRK was the first laser vision correction procedure approved in the United States and remains a safe, effective choice for many patients today. The treatment uses an excimer laser to reshape the cornea so light can focus properly on the retina. Unlike LASIK, which creates a corneal flap, PRK gently removes the outer layer of corneal cells before reshaping begins. This layer naturally regenerates during recovery. Because PRK avoids the creation of a flap, it is often recommended for patients whose corneas are too thin for LASIK. The results are just as precise, and many people experience excellent long-term vision without glasses or contacts. Who Is a Candidate for PRK? PRK may be recommended for patients who want clearer vision but do not qualify for LASIK. Ideal candidates include: People with thin or irregular corneas that make flap-based surgery less safe Active individuals or athletes who may risk corneal injury with LASIK Patients with dry eyes who might not respond well to flap-based procedures Adults with stable prescriptions and healthy overall eye health A thorough eye exam will help determine if PRK is the right choice. Dr. Chu may also simulate expected outcomes so patients can understand the benefits of choosing PRK over other refractive options. Why Choose Cornerstone Eye Associates for PRK Choosing PRK at Cornerstone Eye Associates means placing your care in the hands of a trusted and experienced surgeon. Dr. Claire Y. Chu completed her ophthalmology training at UT Southwestern, served as a clinical instructor for more than 15 years, and has been honored with awards for her dedication to education and patient care.

• Types of IOLs

  Cataract surgery is one of the most common and successful procedures performed today, restoring clear vision by replacing the cloudy natural lens with an artificial lens implant called an intraocular lens, or IOL. The type of IOL selected plays a significant role in how well you see after surgery, especially when it comes to reducing dependence on glasses. With modern technology, patients now have more options than ever before to match their lenses to their lifestyle and visual needs. At Cornerstone Eye Associates, Dr. Claire Y. Chu helps patients understand their choices in IOLs so they can make informed decisions. A board-certified ophthalmologist with a special interest in advanced technology cataract surgery, Dr. Chu combines years of clinical experience, academic contributions at UT Southwestern, and recognition in D Magazine’s Best Doctors List to ensure each patient receives personalized care and excellent outcomes. What Are Intraocular Lenses? An intraocular lens is a clear, artificial lens implanted in the eye to replace the natural lens that has become cloudy from cataracts. These lenses are designed to focus light on the retina, restoring sharp, bright vision. Once implanted, an IOL becomes a permanent part of the eye and does not require maintenance. Different types of IOLs offer unique advantages, and selecting the right one is an important step in preparing for cataract surgery. Types of IOLs Available Several categories of IOLs exist to meet different vision needs: Monofocal IOLs: These lenses provide clear vision at one fixed distance, usually optimized for distance vision. Glasses may still be needed for reading or computer work. Multifocal IOLs: Designed with multiple zones of focus, these lenses allow patients to see at near, intermediate, and far distances, often reducing the need for glasses altogether. Extended Depth of Focus (EDOF) IOLs: These newer lenses stretch the range of clear vision, improving focus at multiple distances while minimizing issues like halos or glare. Toric IOLs: Specially designed for patients with astigmatism, toric IOLs correct irregular curvature of the cornea to provide sharper vision without glasses. Each option has distinct benefits and considerations. Dr. Chu takes time to review your eye measurements, daily habits, and vision goals to recommend the lens that best matches your lifestyle. Why Choose Cornerstone Eye Associates for IOL Selection At Cornerstone Eye Associates, patients benefit from the expertise of Dr. Claire Y.

• Comprehensive Eye Exam

  A comprehensive eye exam is more than just a vision test. While many people associate eye care with updating their glasses or contact lens prescription, a full exam also evaluates the overall health of the eyes. Through advanced testing and careful evaluation, an eye exam can detect early signs of conditions like glaucoma, cataracts, diabetic eye disease, and macular degeneration—sometimes before symptoms are even noticeable. At Cornerstone Eye Associates, we provide thorough, personalized eye exams designed to protect both vision and eye health. Led by Dr. Claire Y.

Recognized in D Magazine’s Best Doctors List and Women of Influence, Dr. Chu offers trusted expertise for patients in Dallas and Richardson seeking proactive eye care. What Is a Comprehensive Eye Exam? A comprehensive eye exam evaluates much more than how clearly you can see. Unlike a simple vision screening, a full exam assesses multiple aspects of eye function and overall health. During your appointment, Dr. Chu may perform tests to: Measure vision and check for refractive errors such as myopia, hyperopia, astigmatism, or presbyopia Examine the cornea, lens, and retina for signs of disease Test eye pressure to screen for glaucoma Evaluate how the eyes work together and track movement Assess overall eye health using advanced imaging when needed This holistic approach helps identify problems early, when they are most treatable. Who Should Have an Eye Exam? Routine eye exams are important for patients of all ages. Recommendations include: Children and teens: Early exams ensure proper vision development and help detect issues that may affect learning. Adults under 40: Every two years, unless vision problems or risk factors are present. Adults 40 to 60: Every one to two years to monitor for age-related changes. Adults over 60: Annually, as the risk for cataracts, glaucoma, and macular degeneration increases. Patients with diabetes or other health conditions: Annual exams are essential to monitor for diabetic retinopathy or related complications. By following these guidelines, patients can protect vision at every stage of life. The Benefits of a Comprehensive Eye Exam Regular exams provide benefits that go far beyond clear sight. They allow for: Early detection of eye disease, even before symptoms occur Updated prescriptions, ensuring the best vision with glasses or contacts Prevention of vision loss, through timely treatment of conditions like glaucoma or retinal disease Assessment of overall health, since exams may reveal signs of systemic issues such as diabetes or high blood pressure Comprehensive care ensures not only sharp vision but also long-term eye health.

• Allergic Conjunctivitis Treatment

  Allergic conjunctivitis is a common eye condition caused by seasonal or environmental allergens. When allergens such as pollen, dust, or pet dander irritate the eyes, the conjunctiva, which is the clear tissue covering the white of the eye, becomes inflamed. Symptoms can range from mild itching to significant redness and swelling, often occurring alongside nasal allergies. While not contagious, allergic conjunctivitis can greatly affect comfort and daily activities. At Cornerstone Eye Associates, patients benefit from precise diagnosis and personalized treatment for allergic eye conditions. Dr. Claire Y. Chu, a board-certified ophthalmologist with more than 15 years of teaching experience at UT Southwestern, provides advanced care tailored to each patient. Recognized in D Magazine’s Best Doctors List and Women of Influence, Dr. Chu offers trusted expertise for patients in Dallas and Richardson seeking relief from allergy-related eye irritation. What Is Allergic Conjunctivitis? Allergic conjunctivitis occurs when the immune system reacts to allergens in the environment. This reaction causes the blood vessels in the conjunctiva to swell, leading to redness, itching, and watery eyes. Unlike bacterial or viral conjunctivitis, allergic conjunctivitis is not contagious and is often seasonal, appearing during spring or fall allergy seasons. For some patients, symptoms can be year-round if triggered by indoor allergens. Symptoms of Allergic Conjunctivitis Symptoms can be mild or severe and often affect both eyes. They may include: Itchy eyes, often the hallmark symptom Redness and irritation, especially after exposure to allergens Watery or teary eyes Swollen eyelids Stringy discharge that differs from the pus seen in bacterial infections Because allergic conjunctivitis can mimic other forms, an eye exam helps confirm the diagnosis and rule out infection. Treatment Options for Allergic Conjunctivitis Treatment focuses on symptom relief and allergen avoidance. Options may include: Artificial tears to rinse allergens from the eyes and soothe irritation Antihistamine or anti-inflammatory eye drops to reduce swelling and itching Cold compresses to ease discomfort Oral allergy medications if symptoms are part of a broader allergic response Avoidance strategies such as keeping windows closed during pollen season or using air filters indoors Dr. Chu develops customized treatment plans to provide effective relief while also protecting long-term eye health.

• Conjunctivitis Treatment

  Conjunctivitis, often called pink eye, is an inflammation of the conjunctiva, which is the clear tissue covering the white of the eye and inside of the eyelids. This condition can be caused by infection, allergies, or irritants, and symptoms often include redness, tearing, and discharge. While many cases are mild, some forms of conjunctivitis are highly contagious and require prompt evaluation to prevent spreading and protect eye health. At Cornerstone Eye Associates, patients with conjunctivitis receive accurate diagnosis and targeted treatment. Dr. Claire Y. Chu, a board-certified ophthalmologist with over 15 years of academic and clinical experience, specializes in both common and complex eye conditions. Recognized in D Magazine’s Best Doctors List and Women of Influence, Dr. Chu provides trusted care for patients in Dallas and Richardson experiencing pink eye. What Is Conjunctivitis? Conjunctivitis occurs when the conjunctiva becomes inflamed. There are several types: Viral conjunctivitis: Usually linked to colds or respiratory infections, highly contagious, and often clears on its own Bacterial conjunctivitis: Caused by bacteria and often treated with antibiotic eye drops Allergic conjunctivitis: Triggered by allergens like pollen or dust, not contagious, and often seasonal Irritant conjunctivitis: Caused by exposure to chemicals, smoke, or foreign bodies Understanding the type of conjunctivitis is critical for effective treatment and preventing unnecessary spread. Symptoms of Conjunctivitis The symptoms vary depending on the cause but may include: Red or pink discoloration of the eye Itching or burning sensation Watery or thick discharge, sometimes causing eyelids to stick together Swollen eyelids Light sensitivity or blurred vision in more severe cases Because conjunctivitis symptoms can overlap with other eye conditions, a professional exam ensures accurate diagnosis and treatment. Treatment Options for Conjunctivitis Treatment depends on the underlying cause: Viral conjunctivitis usually resolves on its own, though cool compresses and artificial tears can ease discomfort Bacterial conjunctivitis may require prescription antibiotic drops or ointment Allergic conjunctivitis is managed with antihistamine or anti-inflammatory drops Irritant conjunctivitis often clears once the irritant is removed, sometimes with the help of lubricating drops Dr. Chu evaluates each patient carefully, offering treatment that not only relieves symptoms but also prevents recurrence.
