Small Aδand C nerve fibers of the sensory and autonomic nervous systems constitute 70–90%of peripheral nerve fibers including corneal nerves(Muller et al.,2003).Corneal nerves originate from the ophthalmic branch of the trigeminal nerve and enter the cornea at the limbus radially from all directions toward the central cornea at the level of anterior and middle *** subepithelial nerve plexus lies at the interface between the Bowman layer and anterior *** then divide into smaller branches and turn 90°toward Bowman’s layer(Muller et al.,2003),travelling between Bowman’s layer and the basal epithelial layer and forming the sub-basal nerve plexus(Muller et al.,2003).

Background:To examine the cosmetic outcome of femtosecond laser-assisted pterygium surgery(FLAPS)with conjunctival autograft(CAG)and its potential predictive ***:This was a prospective interventional case series(NCT02866968).We included 29 patients(29 eyes)with primary pterygium who underwent *** outcome was graded by two graders(an ophthalmology resident and an experienced ophthalmologist)using Hirst classification system(1-4=excellent-poor).Weighted Cohen’s kappa analysis was performed to examine the intra-and inter-rater *** relationship between cosmetic outcome and various factors were determined by Spearman’s correlation coefficients(r).Results:The preoperative severity of pterygium(Tan grading system)was mild/atrophic(7%),moderate/intermediate(62%),and severe/fleshy(31%).An ultrathin CAG(mean thickness of 74.5±9.8μm)was fashioned *** excellent cosmetic outcome of FLAPS(median±IQR)was observed at 3 months(1.0±1.0)and remained similar at 6months(1.0±0.0)and 12months(1.0±0.0)*** final follow-up,27(93%)patients achieved good-to-excellent cosmetic outcome,with 1(3%)patient having a poor outcome due to incomplete pterygium *** kappa analysis of Hirst grading system showed excellent intra-rater(κ=0.86-0.95)and inter-rater reliability(κ=0.84-0.88).There was a weak and borderline significant correlation between good cosmetic outcome and reduced postoperative CAG thickness(r=0.38,P=0.06)but not with age,gender,preoperative pterygium severity,or intraoperative CAG ***:FLAPS can result in an excellent cosmetic outcome,which may be attributed to the beneficial effect of an ultrathin CAG.
