Laser refractive surgery is a procedure used to correct vision problems such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. It involves using a laser to reshape the cornea, which is the clear front part of the eye, to improve vision.
Below is some important information you should know before undergoing laser refractive surgery.
Types of Laser Refractive Surgery:
1. LASIK (Laser-Assisted In Situ Keratomileusis):
o LASIK is the most common type of laser refractive surgery.
o During the procedure, a thin flap is created on the cornea using a microkeratome or a femtosecond laser. The flap is then lifted, and the underlying corneal tissue is reshaped using an excimer laser. Finally, the flap is repositioned. Contoura LASIK refers to customized laser treatment using topography guided data.
o LASIK typically results in rapid visual recovery and minimal discomfort.
2. PRK (Photorefractive Keratectomy):
o PRK is an alternative to LASIK, suitable for patients with thinner corneas or other corneal irregularities.
o Instead of creating a flap, the outer layer of the cornea (epithelium) is removed entirely before reshaping the cornea with an excimer laser. Contoura PRK refers to customized laser treatment using topography guided data.
o PRK may have a longer recovery period compared to LASIK, with some discomfort during the initial healing phase.
3. CLEAR (Small Incision Lenticule Extraction):
o CLEAR is a newer type of laser refractive surgery that involves creating a small incision in the cornea to remove a lenticule of tissue, thereby reshaping the cornea.
o Unlike LASIK and PRK, CLEAR or SMILE does not require the creation of a corneal flap, potentially resulting in faster recovery and reduced risk of certain complications.
Candidates for Laser Refractive Surgery:
• Good candidates for laser refractive surgery generally have stable vision prescriptions and healthy eyes.
• Candidates must be over 18 years old (sometimes older depending on the procedure) and have realistic expectations about the outcomes of the surgery.
• Certain medical conditions such as autoimmune disorders, severe dry eye, or unstable diabetes may disqualify individuals from undergoing laser refractive surgery.
Risks and Complications:
• While laser refractive surgery is generally safe and effective, there are potential risks and rare complications, including:
o Dry eyes o Glare or halos around lights, especially at night o Undercorrection or overcorrection of vision
o Flap complications (specific to LASIK)
o Infection
o Corneal haze (specific to PRK)
• It's essential to discuss these risks with your eye surgeon before making a decision.
Preparation and Recovery:
• Before the surgery, your eye surgeon will conduct a thorough eye examination to determine your suitability for the procedure.
• You may need to stop wearing contact lenses for a period of time before the surgery.
• After the surgery, you may experience some discomfort, but this typically subsides within a few days to a week.
• Follow your surgeon's post-operative instructions carefully, including using prescribed eye drops and attending follow-up appointments.
Cost and Insurance:
• Laser refractive surgery is usually considered an elective procedure and may not be covered by insurance.
• The cost of the surgery can vary depending on factors such as the type of procedure, the technology used, and the surgeon's experience.
Conclusion:
Laser refractive surgery can be a life-changing procedure for many individuals, providing freedom from glasses or contact lenses. However, it's essential to weigh the potential benefits against the risks and to have realistic expectations about the outcomes. Consult with a qualified eye surgeon to determine if you are a suitable candidate for laser refractive surgery and to discuss which procedure may be best for you.
