98 Clinical Poster SessionsMedian visual acuity score in both the groups was matched at the baseline (p=0.17) and the finalmedian visual acuity score was not statistically different both the groups (intergroup (p=0.89)and intra group (p=0.56) analysis). None of the patients had recurrence in the observationgroup while one patient had recurrence in the treatment group.Conclusions: Steroids does not affect the visual outcome of APMPPE nor do they have muchinfluence in preventing recurrences.ICP 015Advanced Assessment of Corneal Biomechanical Properties in Normal andKeratoconic Eyes using the Ocular Response Analyzer (ORA)Kunjal Sejpal, Johnson Duncan, Yu Fei, Hamilton D RexJules Stein Eye Institute, UCLA, Los Angeles, USAPurpose: To evaluate corneal biomechanics in normal and keratoconus subjects by analysis ofwaveform parameters obtained from the ORA(Reichert Instruments).Methods: Retrospective, comparative case series between April 2005 and April 2009. ORAwaveform parameters (41) were compared between groups of patient with manifest keratoconusand normal corneas, which were age and gender matched. The KCN group included patientswith manifest keratoconus based on the Keratoconic Severity Score of 3 or more.Results: 73 eyes of 54 keratoconus (KCN) subjects and 115 eyes of 115 normal subjectswere included. Mean Corneal Hysteresis (CH) was 8.1+1.5 mm Hg in KCN and 11+1.6 mmHg in normal eyes (p
