LASIK is usually considered the better option than PRK for correcting severe nearsightedness (myopia). However, there is also a need to know what is photorefractive keratectomy (PRK)?
Photorefractive keratectomy, abbreviated as PRK, refers to laser eye surgery that reduces the requirement for wearing corrective eyewear by reshaping the cornea. It also helps in changing the way the eye light lets light focus on the retina. In this procedure, under the supervision of Dr Piyush Eye Specialist, the excimer laser removes a thin layer of the cornea, thus changing the cornea’s refractive power.
Vision problems that photorefractive keratectomy treat
PRK treats a variety of refractive errors, including myopia that is commonly referred to as nearsightedness, hyperopia, farsightedness, and astigmatism, which refers to the imperfection in the eye’s curvature. Medical conditions affecting the eye’s surface include Salzmann’s nodules and recurrent erosions. In this regard, Photorefractive Keratectomy can treat numerous issues. Physicians from the bet Lasik Laser Surgery In Janakpuri clinic, the Healing Touch Eye Centre, use the laser for indications, and this is the procedure that is referred to as phototherapeutic keratectomy, abbreviated as PTK.
Determining a good candidate for PRK
The ideal candidate refers to the individual whose corneal tissue is suited for the procedure. However, before the process starts, it’s essential to determine that the Patients meet several criteria. Corneal thickness consideration is important. Also, it’s worth noting that the larger corrections require more tissue ablation. The other thing one must note is that the eye doctor reviews the medical history and performs eye examination for finding the eye problems or medical conditions affecting the outcome. Poor eye health and also certain medical diseases increase the risk. It is always good to make an appointment with an eye doctor from a clinic like Healing Touch Eye Centre which is the most reputed Myopia Clinic In Delhi. The ophthalmologists will ensure a better examination of the eyes and find out the best surgical procedure based on your eyes condition.
You can rest assured that the effects of PRK are permanent. But, there may be a chance that the vision change after surgery for age-related cataracts. Although LASIK turns out to be more popular than PRK, LASIK doesn’t prove to be a suitable option for all candidates.
