Abstract Details


To compare prognosis of keratoconus according to the indices, the corneal thickness and anterior chamber depth


Department of Ophthalmology and Visual Science, St. Mary's Hospital, The Catholic University of Korea College of Medicine, Seoul, Korea


A total 80 eyes of 73 keratoconus patients who are 20~25 aged was with followed up period of more than 2 years were included. Mean central K reading of All included patient was more than 48D. Videokeratographic data were obtained by computerized Videokeratography (Orbscan IIz; Bausch & Lomb Surgical, Rochester, NY), which is a three-dimensional slit-scanning topography system that is used to analyze the corneal anterior and posterior surfaces and for performing pachymetry. Patients were classified into four groups by corneal thickness and anterior chamber depth: Group 1 (corneal thickness ≥450㎛, Anterior chamber depth<3.50mm), Group 2 (corneal thickness<450㎛, Anterior chamber depth≥3.50mm), Group 3 (corneal thickness<450㎛, Anterior chamber depth<3.50mm), Group 4 (corneal thickness≥450㎛, Anterior chamber depth≥3.50mm). Change of indicies (corneal thickness, anterior chamber depth) were analyzed among the groups.


Among the groups, thin corneal thickness patients with deep anterior chamber depth(Group 2) is showed more change in each indicator, the ongoing trend


In Keratoconus patient, corneal thickness and anterior chamber depth seems be useful indicies as a predictor of prognosis of keratoconus, and enable to convenient to decision direction of treatment plan including surgical intervention. FINANCIAL INTEREST: NONE
