PRK has advantages over LASIK in that it avoids added complications associated with the flap created during surgery. The procedure may also reduce the chances of dry eye symptoms after surgery. Due to the PRK procedure not requiring a surgical flap, athletes or individuals concerned with trauma introduced by the flap may see benefits to LASEK ...
Individuals with atopic conditions with pre-existing allergic conjunctivitis, or ocular rosacea, are more prone to developing the condition after surgery. Some authors have reported that moderate to severe eye allergies and chronic allergic conjunctivitis are an absolute contraindication to the LASIK procedure. [ 3 ]

The Edwin Smith Papyrus is a lesser known papyrus dating from the 1600 BCE and only 5 meters in length. It is a manual for performing traumatic surgery and gives 48 case histories. [12] [18] The Smith Papyrus describes a treatment for repairing a broken nose, [19] and the use of sutures to close wounds. [20] Infections were treated with honey. [21]
[7] [8] [9] The risk is estimated to be between 0.25% [6] and 0.7% [10] Healing of the RK incisions is very slow and unpredictable, often incomplete even years after surgery. [11] Similarly, infection of these chronic wounds can also occur years after surgery, [12] [13] [14] with 53% of ocular infections being late in onset. [15]
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.
No treatment modality prior to neurectomy (e.g. systemic medications, cryoablation, therapeutic nerve blocks, and radioablation) has given effective pain relief and none have been curative. [ 19 ] The success outcome is typically measured as a 50% or more decrease in visual analog scale (VAS) scores, which are numerical pain scores from 0 - 10 ...
