Phototherapeutic keratectomy (PTK) is a laser procedure to treat corneal conditions such as scars, irregularities, or cloudiness. Using an excimer laser, Dr. Hu removes microscopically thin layers of damaged corneal tissue with precision, leaving the surrounding tissue intact. The corneal surface is then smoothed, allowing new tissue to regenerate naturally. PTK is a safe and effective alternative to corneal transplants for many patients, offering faster recovery and long-term relief from discomfort and vision issues.
Phototherapeutic keratectomy (PTK) is a minimally invasive laser procedure that treats corneal irregularities, scars, or cloudiness. Unlike a corneal transplant, PTK does not involve removing and replacing the entire cornea. Instead, an excimer laser removes only the damaged layers of tissue, leaving the rest of the cornea intact. This approach offers faster recovery, with most patients resuming normal activities within days.
A corneal transplant involves surgically replacing a damaged or diseased cornea with donor tissue. This procedure is often necessary for severe corneal conditions, such as advanced keratoconus or significant structural damage that PTK cannot address. While a transplant can restore vision in severe cases, recovery is longer, taking months for full results. Additionally, the procedure carries a higher risk of complications, such as graft rejection or infection.
Your PTK session begins with applying anesthetic eye drops to numb the cornea. A lid speculum is used to keep your eye open during the procedure. Dr. Hu uses an excimer laser to vaporize and remove microscopic layers of damaged corneal tissue, targeting irregularities, scars, or cloudiness. After smoothing the cornea, a contact lens bandage is placed to protect the surface and promote epithelial regeneration. The procedure typically lasts less than 30 minutes.
After your PTK procedure with Dr. Hu, temporary side effects like blurry vision, mild discomfort, or sensitivity to light are normal. To ensure a smooth recovery, Dr. Hu will provide you with medicated eye drops and pain management instructions. You must avoid touching your eyes and may take a few days off from work or daily activities. As your cornea heals, your vision will gradually improve, with maximum correction typically achieved within six months.
With PTK, Dr. Hu aims to restore your vision and alleviate discomfort caused by corneal irregularities. You can expect significant improvement in visual clarity as damaged corneal tissue is removed and healthy tissue regenerates. Many patients notice initial improvement within days, with vision continuing to sharpen over the following weeks. By six months, most achieve optimal results, including reduced visual distortions and improved light sensitivity.
No, the PTK procedure is not painful. Dr. Hu applies anesthetic eye drops to numb your eye, ensuring you remain comfortable throughout. Some mild discomfort or irritation may occur during recovery, but this is managed with prescribed medications and eye drops.
Most patients experience noticeable improvement in a few days, with maximum vision correction achieved within six months. You’ll need to take a few days off from work or strenuous activities and closely follow Dr. Hu’s recovery instructions to promote healing.
After PTK, avoid rubbing or touching your eyes and follow Dr. Hu’s instructions for applying medicated eye drops. Protect your eyes from bright light and wear sunglasses outdoors. Avoid swimming or exposing your eyes to potential irritants until cleared by Dr. Hu.
The results of PTK are long-lasting, particularly for conditions like corneal scars or recurrent erosion syndrome. However, depending on your eye health and individual response to the procedure, some conditions may require follow-up treatments or additional care.
