Farsightedness, nearsightedness, astigmatism, and presbyopia are all common vision issues. Refractive surgery is used to treat such issues, as it reduces the need for contact lenses or glasses. Lasik surgery is one of the most effective surgical techniques for these eye conditions. For more information on types of Lasik treatments, check out the specialists like Personal Eyes Lasik Surgery.
Why is Lasik Performed?
Blurred vision occurs when light does not focus properly on the retina. This is called a refractive error. Some basic types are:
- Astigmatism (myopia): Things in the distance are clearer, while things up close seem hazy.
- Foresight (hyperopia): Things far away are clearer, yet things close up are hazy.
- Astigmatism: Due to the shape of your eyes, this might make everything hazy.
The following are the different types of Lasik surgery you can expect from a specialized clinic to treat the conditions mentioned above.
The most popular laser vision repair surgery is standard Lasik. A microkeratome blade is used to carve a small flap in the top layer of the cornea. After carefully pulling back the flap, the doctor uses an excimer laser to restructure the corneal layers.
This Lasik procedure is painless and safe for patients with light to moderate prescriptions. It can correct eyesight within 24 to 48 hours, while vision improves for weeks after the treatment.
Custom Lasik has helped individuals see better since its inception. However, before contemporary computer technology, there was far more risk. Lasik was once only based on your prescription. This approach was still effective, but it lacked precision when restoring vision.
These days, clinics have wavefront-guided Lasik, which creates a near-perfect map of your eye’s surface. This data is used during surgery to precisely remodel the surface of your eye, allowing you to see much better than before.
PRK (Photorefractive Keratectomy)
Unlike Standard Lasik and Custom Lasik, a corneal flap is not generated for PRK. Instead, a solution is used to loosen and remove a thin layer of corneal cells gently. The remaining corneal layers are reshaped with an excimer laser.
Pain is common during the cell regrowth period. After the procedure, the doctor may advise the patient to wear a bandage contact lens for several weeks. It protects the thin layer of re-growing cells.
Although PRK can be performed on anyone with healthy eyes, it is most usually recommended for people with thin corneas or at risk of being hit in the face or eyes.
Are You Fit for Lasik?
A patient’s corneal thickness must be adequate for Lasik. Because a flap is generated during the process, thin or uneven corneas may not obtain the treatment. Patients with thin or uneven corneas might consider SMILE or PRK.
SMILE or PRK may be preferable options for patients who suffer from persistent dry eye. Lasik is known to enhance postoperative dry eye symptoms and exacerbate chronic dry eye.
Choosing the right clinic when undergoing Lasik surgery becomes critical, as not all clinics offer quality treatment. Do your research and choose a compatible specialized clinic like Personal Eyes Lasik Surgery for fast and effective results if you are stone-set on Lasik surgery.
