Lasik is a vision-correction procedure that reduces dependence on glasses or contact lenses by reshaping the cornea to improve how light focuses on the retina. While the surgery is quick, outcomes depend on careful screening, realistic expectations, and appropriate aftercare. Here is what to expect from Lasik eye surgery:
Screening for Lasik
The first step in Lasik procedure involves a comprehensive eye exam to determine if a patient is a suitable candidate. This includes measuring corneal thickness, checking eye pressure, and mapping the corneal shape. Doctors also review the patient’s medical history to look for conditions that may affect healing, such as autoimmune diseases or severe dry eye. Candidates generally need to be at least 18 years old, though some clinics prefer patients to be over 21. This requirement exists because vision can continue to change into early adulthood.
Going Through Surgery
Lasik surgery is a quick outpatient procedure that involves specific steps to make sure the patient is comfortable and the correction is precise. Here is what you can generally expect during the procedure:
- Anesthetic Application: The process starts with numbing eye drops to prevent pain, and sometimes a mild sedative is given for relaxation.
- Eyelid Holder Placement: A special instrument gently holds the eyelids open to prevent blinking during the laser application.
- Flap Creation: The surgeon uses a femtosecond laser or a microkeratome blade to create a thin, hinged flap on the cornea’s surface.
- Laser Reshaping: The surgeon lifts a flap and removes microscopic amounts of tissue, reshaping the cornea according to the patient’s prescription.
- Flap Repositioning: The flap is repositioned and adhered naturally without the need for stitches.
After the procedure, the doctor performs a final check to confirm that the flap is correctly positioned before releasing the patient to go home.
Healing and Aftercare
Immediately after the Lasik procedure, patients may experience mild discomfort; symptoms may include a gritty sensation, watering, light sensitivity, or a feeling that something is in the eye. Doctors advise patients to go home and nap for a few hours to rest their eyes. Using the provided protective eye shields while sleeping prevents accidental rubbing, which can dislodge the corneal flap.
The first follow-up appointment usually happens 24 hours after surgery. During this visit, the doctor checks visual acuity and examines the eyes for signs of infection or complications. Patients must adhere to a strict eye drop schedule. This regimen includes antibiotic drops to prevent infection and steroid drops to control inflammation.
Monitoring Results
While laser eye surgery has a high success rate, understanding the potential outcomes and risks is part of the decision-making process. Here is what you can expect from the procedure:
- Visual Improvement: Most patients achieve 20/20 vision or better, though some may still need glasses for specific activities, such as reading or driving at night.
- Temporary Side Effects: Common issues include glare, halos around lights, dry eyes, and fluctuating vision, which typically resolve within a few weeks to months.
- Undercorrection or Overcorrection: In some cases, the laser may remove too little or too much tissue, requiring a second enhancement surgery.
- Flap Complications: Issues with the corneal flap, such as infection or improper healing, are rare but can affect vision if they occur.
- Regression: Over time, vision may change slightly, leading to a return of nearsightedness or farsightedness.
If severe pain occurs or if vision suddenly worsens rather than improves, contacting the doctor immediately is fundamental.
