Lasik Eye Surgery Complications
Overview
While the risks associated with Lasik eye surgery are generally low when performed by an experienced surgeon, it's crucial to be informed about potential complications. Your surgeon should openly discuss these risks ahead of time. Some complications include infection, undercorrection, overcorrection, dry eye, corneal abrasions, night glare, and corneal flap issues. Learn which complications might resolve naturally and which could require further surgery.
Potential Complications
Undercorrection
Undercorrection occurs when the desired vision correction isn’t fully achieved. This is more common in patients with a high degree of nearsightedness, farsightedness, or astigmatism due to the extensive corneal reshaping required. Ensure your surgeon shares the percentage of patients needing retreatment for undercorrection. Note: a planned slight undercorrection for nearsighted patients over 40 may be discussed to aid reading vision.
Overcorrection
Overcorrection is less frequent and happens when the correction exceeds the plan. Mild overcorrections may resolve within a month, and temporary glasses can help. Severe cases might need additional surgery 3-6 months later.
Dry Eye
Many patients experience a gritty sensation post-surgery, usually resolving within 3-6 months. Lubricating eye drops can help. Those using birth control pills or undergoing menopause might be more susceptible. If dry eye persists beyond 6 months, silicone plugs may be recommended to conserve tears.
Corneal Abrasion
A minor percentage may develop a corneal abrasion caused by the microkeratome during surgery. These abrasions are typically minor and heal quickly, sometimes aided by a thin bandage contact lens. Vision may be blurry as the abrasion heals.
Night Glare
Some patients experience halos or ghost images at night initially. This condition usually improves within 3 months and often disappears by the 6-month mark. It can be more pronounced in patients with large pupils or severe vision impairment.
Corneal Flap Issues
Complications with the corneal flap can occur if it's too small, thin, or irregularly shaped. Flap displacement from rubbing the eyes shortly after surgery can cause wrinkles, distorting vision. A corrective procedure may be needed.
Infection
Although rare, infection is a serious concern. It typically occurs within 72 hours post-surgery and is treated with antibiotic eye drops. Avoid eye makeup, hot tubs, and swimming pools for at least the first week to minimize risk.
Final Thoughts
Lasik surgery comes with low risks when conducted by a skilled surgeon, but understanding potential complications is essential. Open communication with your surgeon is vital to ensure your eyes are in trusted hands.
