LASIK, or laser in-situ keratomileusis, is an effective surgery to improve vision in people who are nearsighted, farsighted, or cylindrical. Although this treatment is quite safe, patients need to be aware of possible complications before undergoing LASIK surgery.
Some of the LASIK complications that may occur after eye surgery
1. Dry eyes
Dry eye is one of the most common complications of LASIK. During the cutting of the outer layer (flap) of the cornea, some parts of the cornea that are responsible for producing tears can be damaged. This results in decreased tear production and exposes LASIK patients to dry eye syndrome.
Symptoms of dry eye can include pain, pain, eye irritation, sticking to the eye ball, blurred vision. Dry eye due to LASIK is usually temporary. This condition often persists during the first 6 months after LASIK surgery and disappears when the eye is fully healed. Eye drops and other means can be used to treat this symptom effectively during this time.
However, the FDA website has warned that dry eye due to LASIK can be permanent in some cases. People who basically have dry eyes are often discouraged from undergoing LASIK.
2. Complications of the flap
During surgery, the flap on the front of the eye is removed so that the laser can reshape the cornea of the eye. Removing this flap can lead to complications, including infection, inflammation, and excessive tearing.
The flap is then replaced and acts as a natural bandage until it sticks back to the cornea. If the flap is not made properly, it cannot adhere properly to the cornea and striae, and microscopic wrinkles can appear on the flap. This results in reduced quality of vision.
Choosing an experienced ophthalmologist can reduce the risk of LASIK complications.
3. The cylinder is irregular
It can result from irregular healing or if the laser is not focused properly on the eye, creating an uneven surface at the front of the eye. This can cause double vision. In this case, the patient needs repeated treatment.
4. Keratectasia
This is a very rare but serious complication of LASIK. This is a condition in which the cornea abnormally protrudes forward. This occurs if the cornea before LASIK is too weak or if too much tissue is removed from the cornea.
5. Sensitive to light
Patients may experience loss of sensitivity to contrast and difficulty seeing clearly at night. They may not be able to see as clearly or sharply as before and also see glowing circles around light, glare, and blurred vision. Fortunately, in most cases, this problem is temporary and will go away in 3 to 6 months.
6. Undercorrection, overcorrection, regression
Undercorrection / overcorrection occurs when the laser removes too little / too much corneal tissue. In this case, the patient will not get the clear vision they expect and will still have to wear glasses or contact lenses for some or all of the activities.
Other reasons for less than perfect results are that your eyes do not respond to treatment as expected or they may regress over time due to overheating.
