ICP 040Clinical Poster SessionsComplications Associated with Different Types of Contact Lens in a Tertiary <strong>Eye</strong>CentreTumati Naga Chandrika, A Uday, D SrikanthL V <strong>Prasad</strong> <strong>Eye</strong> <strong>Institute</strong>, Hyderabad, India113Purpose: To determine the Prevalence of contact lens related complications in a Tertiary <strong>Eye</strong>Centre.Methods: It is a Retrospective study in which 1255 Medical records were reviewed to identifythe complications caused due to the contact lens wear ,of which 190 subjects records werenoticed to have complications.Results: Prevalence of complications like Contact lens-induced papillary conjunctivitis,Corneal hypoxia and Superficial punctate staining were 31%,19.48%,16.86%.our study showscomplications were less prevalent in patients wearing Rigid gas permeable lenses, Soft monthly,Soft Biweekly, Daily disposable lenses and patients wearing Soft conventional lenses showedhighest rate of complications.Conclusions: Highest rate of complications were found with Soft conventional lenses.Choice of Lens type, Wearing schedule, Time period, Care system will affect the prevalence ofcomplications.ICP 041A New Computer Based Test for Clinical Evaluation of Color VisionTwinkle Parmar, Supriyo Ghose, M Vanathi, Dinesh Shrey, Tanuj DadaDr Rajendra <strong>Prasad</strong> Centre for Ophthalmic Sciences, AIIMS, New Delhi, India.Purpose: To evaluate the computer based Fansworth Munsell (FM) 100-Hue test andits comparison with manual FM-100 Hue test in normal and congenitally color deficientindividuals.Methods: Fifty color defectives [M:F=49:1; age 29.5±9.5(17-45) yrs] and 200 normal subjects[M:F=129:71; age 28.2±8.0(19-39) yrs] with BCVA = 6/12 were subjected to manual andcomputer based FM 100 Hue test after initial trial testing in a randomized manner understandard operating conditions recommended by the manufacturer. Parameters evaluated weretotal error scores (TES), type of color defect and time taken to perform the test.Results: Mean testing time was 16 ± 1.49 (6-20) and 7.40 ± 1.39(5-13) min with manual andcomputer based FM 100-Hue test respectively, thus reducing testing time to less than half withthe computer based automated software. Karl Pearson’s correlation coefficient for TES with thetwo tests for grading color discrimination was 0.9122 (p
