Types of LASIK
In rare scenarios, patients are not adequate subjects for LASIK surgery. However, this doesn’t mean all hope is lost. Just because you have a cornea that’s too thin or a prior injury to the eye, you don’t have to go without corrective surgery. Instead, there are options and choices available to these outlier situations.
The first alternative is PRK or photorefractive keratectomy. This procedure is one in which laser correction is used to address hyperopia, myopia, and astigmatism. This procedure does not involve creating a flap over the cornea. Instead, the top cells of the cornea are removed, and the excimer laser goes to corrective reshaping. A contact lens – specifically a healing bandage synthetic lens – is put in place for about a week. Unfortunately, this method takes significant time to reach its full potential and for patients to gain corrective sight. But in the end, the procedure’s outcomes are reported to match those of LASIK outcomes.
LASEK surgery addresses three primary concerns: farsighted vision, nearsightedness, and astigmatism. It is a similar procedure to PRK, but it differs in that the corneal surface layer gets a total replacement after surgery. This corneous layer is technically called the epithelium. This procedure is an ample alternative to LASIK, as it works less invasively within the eye.
In a LASEK surgery, the top layer of the cornea is pulled back, so the cornea itself is exposed. The laser then reshapes the cornea. Then that top layer is replaced and covered with a bandage contact lens. This lens initiates the healing and recovery, which is sometimes a little more uncomfortable than the healing from a LASIK.
An alternative to the above-listed procedures is a PHAKIC IOL. This method is a direct result of a patient’s inability to receive LASIK because of extreme levels of myopia or hyperopia. LASIK would not work for this patient, as their eyes were not stable enough to endure cornea reshaping. As a solution, PHAKIC IOL was invented. Instead of reshaping the cornea, this procedure addresses the eye’s lens, much like a cataract surgery.
PHAKIC IOLinvolves using an IOL (intraocular or artificial lens). The IOL is placed on top the natural one, which renews the focusing skill of the eye, and often provides correction of myopia or hyperopia.
All Eyes Are Different
Due to the nature of our humanity, and the fact that all eyes are different in both shape and skill, it makes sense that alternatives to LASIK surgery exist. Your Eye Specialists offers these surgeries alongside LASIK to ensure the best in patient eye care.
