As with other forms of refractive surgery, keratoconjunctivitis sicca, colloquially referred to as 'dry eye,' is the most common complication of PRK, and can be permanent. In more advanced cases, recurrent erosions occur during sleeping from adherence of the corneal epithelium to the upper eyelid with rapid eye movement .
Clear lens extraction, also known as refractive lensectomy, custom lens replacement or refractive lens exchange is a surgical procedure in which clear lens of the human eye is removed. Unlike cataract surgery , where the cloudy lens is removed to treat a cataract , clear lens extraction is done to surgically correct refractive errors such as ...
Refractive surgery is an optional eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses. This can include various methods of surgical remodeling of the cornea ( keratomileusis ), lens implantation or lens replacement.
An FDA draft suggests LASIK surgery patients be better warned of potential complications. Experts explain potential laser eye surgery side effects.
One conspicuous difference between SMILE and LASIK is the size and shape of the corneal incision. In LASIK, the surgeon performs a 270-degree, 20 mm long incision, while in SMILE the so-called "side cap cut", which is the incision through which the surgeon extracts the lenticule, is usually about 4 mm long.

According to the PERK study, 58% of eyes were corrected within 1.00D of goal 3 years after surgery. Additionally, 76% of eyes had uncorrected vision of 20/40 or better at 3 years. [ 5 ] From 2 to 10 years post-operatively 43% of eyes had an increase in farsightedness by 1.00D or more.
Patients should avoid driving for at least 24 hours after the surgery, largely due to effects from the anaesthesia, possible swelling affecting focus, and pupil dilation causing excessive glare. At the first post-operative check, the surgeon will usually assess whether vision is suitable for driving.
Epikeratophakia [1] (also known as epikeratoplasty and onlay lamellar keratoplasty [2]) is a refractive surgical procedure in which a lamella of a donor cornea is transplanted onto the anterior surface of the patient's cornea. A lamellar disc from a donor cornea is placed over the de-epithelialized host cornea and sutured into a prepared groove ...
