Keratoconus is a corneal disease characterized by progressive thinning and protrusion of cornea.1In patients with progressive keratoconus with a clear central cornea and thinnest corneal thickness >400 microns, corneal cross-linking (KXL) can reduce the risk of progression.2 Keratoconus is a localized disease hence the treatment should be localized and not uniform.3 However, the mechanisms underlying the focal disease and the effect of the molecular factors on treatment outcomes remain unknown.

Laser In Situ Keratomileusius (LASIK) is the most commonly performed procedure for correction of refractive error. Its safety and efficacy has been established with numerous studies. Femtosecond laser has improved flap creation and allowed customisation which was not previously available with conventional LASIK.

FP1462: Topoguided Laser Treatment of Iatrogenic Irregular Cornea – A Study

Dr.Narayan Bardoloi, N03755

Being essentially a cosmetic procedure the patients after laser procedure are very sensitive if the result is not perfect.. Aside from residual refractive error or overcorrection, theses patients frequently have some form of irregular astigmatism induced by small optical zones and or decentered  ablation. These types of refractive errors are difficult to correct with standard treatments because of their irregular nature. These types of patients would benefit from either wave front guided or topo-guided ablation.
