Post-LASIK dry eye

Abstract

Laser-assisted in situ keratomileusis (LASIK) is a frequently performed corneal refractive surgery with excellent refractive outcomes. The most common complication of LASIK is dry eyes, with virtually all patients developing some degree of dryness in the immediate postoperative period. Identifying preoperative dry eyes, and conscientious attention and treatment in the perioperative time period, can lead to enhanced patient satisfaction and more accurate visual outcomes. Improved understanding of the development of dry eyes after LASIK will advance our understanding of the complex pathophysiology of dry eye disease.

“…9,10 Immediately after LASIK, 95% of patients report some dry eye symptoms. 11 The LASIK-induced change in corneal shape may affect the relationship between the eyelids and ocular surface and lead to abnormal tear distribution during blinking.…”

“…LASIK disrupts both the dense sub-basal nerve plexus and stromal corneal nerves in the creation of the anterior stromal flap and excimer laser ablation of the cornea. 9 Though with the use of femto-second laser the complications associated with the micro-keratome are reduced, an association of use of the laser with the early post-operative SPKs is yet to be determined. SPKs in such scenarios are mainly an outcome of chronic inflammatory environment of the cornea.…”

“…Adding to which loss of corneal sensations for first few months can play a role in occurrence of late post-operative SPKs leading to a dry eye. 9 But whether any of these factors play any role in early pre-operative SPKs is yet to be proven. It is likely that mechanism behind the early pre-operative SPKs are related to immediate intra-operative events.…”

Dry Eye Epidemiology in Patients before Refractive Operations

“…Keywords Синдром «сухого глаза» (ССГ) является наиболее распространенным нежелательным явлением после лазерных рефракционных вмешательств на роговице (PRK; LASIK; ReLEx) [1][2][3][4][5][6]. Максимальная частота этого варианта ССГ (от 35 до 60%) отмечается после операций, выполненных по технологии LASIK [2,3,6].…”
