LASEK (Laser-Assisted Sub-Epithelial Keratectomy) is a modern eye surgery that reshapes the cornea, the clear front part of the eye, to improve vision. This procedure is popular among people with refractive errors such as nearsightedness, farsightedness, and astigmatism.
During LASEK surgery, the doctor uses a special laser to gently remove a thin layer of cells from the surface of the cornea. This allows the laser to reshape the underlying corneal tissue, correcting the vision problem. Unlike other procedures, LASEK preserves more of the corneal surface, which can lead to a faster recovery.
After surgery, patients often experience less discomfort than with traditional LASIK. Recovery time can vary, but many notice improvements in their vision within a few days to a week. Eye drops and protective contact lenses are commonly used to promote healing and reduce discomfort. LASEK is a safe and effective procedure, but it’s important to consult with an eye care professional to see if you are a good candidate. Overall, LASEK provides an opportunity for clearer vision and less dependence on glasses or contact lenses.
People who are considering LASEK surgery typically have the following vision issues:
Nearsightedness (Myopia): Difficulty seeing distant objects clearly.
Farsightedness (Hyperopia): Trouble seeing close objects.
Astigmatism: Blurred vision caused by an irregularly shaped cornea.
In addition, potential candidates often experience:
Frequent changes in prescription glasses or contact lenses.
Dependence on corrective eyewear.
Refractive errors occur when:
The shape of the eyeball is too long or too short.
The cornea is not curved correctly.
The lens does not focus light correctly.
These conditions are often hereditary but can also be influenced by environmental factors, eye injuries, or diseases.
If you notice significant changes in your vision or have trouble with daily activities because of your eyesight, it's important to seek medical care. An eye specialist will assess your vision and determine if you're a good candidate for LASEK.
Certain factors can increase the risk of complications from LASEK surgery:
Age: Patients should generally be at least 18 years old.
Certain health conditions, such as autoimmune diseases or uncontrolled diabetes.
Thin corneas.
Severe dry eyes.
Previous eye surgeries.
Before LASEK surgery, the following tests may be conducted:
Comprehensive Eye Exam: To assess vision and eye health.
Corneal Thickness Measurement: Ensure the cornea is thick enough for the procedure.
Pupil Size Measurement: To understand how the eyes respond to light.
Wavefront Analysis: To create a detailed cornea map and identify any irregularities.
Do's:
Follow your doctor's pre-surgery instructions carefully.
Use prescribed eye drops as directed.
Attend all follow-up appointments.
Wear sunglasses to protect your eyes from bright light.
Don'ts:
Avoid rubbing your eyes after surgery.
Do not swim or use hot tubs for at least 2 weeks after surgery.
Avoid eye makeup for a week or as advised.
Steer clear of strenuous activities and heavy lifting for a few days.
