112 Clinical Poster SessionsPurpose: To report the role of Boston Ocular Surface Prosthesis (BOSP) in a case ofKeratoconus associated with VKC.Methods: A 20year-old gentleman presented with burning sensation, photophobia,dimness ofvision redness and discomfort in both eyes from last 6 years.Uncorrected visual acuity (UCVA)was 6/48 which improved to 6/36 with the manifest refraction in right eye and 6/120 improvedto 6/36 in left eye.Slit lamp biomicroscopy revealed signs of VKC and features of keratoconus.He used piggyback lens system in the past for 5 months in both eyes but discontinued dueto discomfort. With Rose K2 trial lens visual acuity improved to 6/15 and 6/18 in right eyeand left eye respectively.The fit was stable with three point touch fluorescein pattern but thepatient had discomfort because of lens awareness. BOSP trial was done in both eyes.The fitwas assessed immediately after lens wear,one hour and three hours of lens wear by noting thehaptic compression before lens removal and conjunctival staining pattern after lens removal.The best corrected visual acuity was assessed with BOSP of various front surface eccentricityvalues.Results: Visual acuity improved to 6/9 and 6/12 in RE and LE respectively with 0.800eccentricities, and the discomfort reduced.There was no untoward complication secondary toBOSP wear such as infectious keratitis.Conclusions: BOSP plays a role in management of patients have vernal keratoconjunctivitisco-existing with keratoconus where the tolerance to RGP lens is poor due to either activedisease or associated dry eye.ICP 039Is 23 g Vitrectomy Cost Effective in Developing Countries?Taraprasad Das, B R Shamanna, Raja NarayananLV Prasad Eye Institute, Bhubaneswar, India.Purpose: Cost effectiveness of 23 g vitrectomy was compared with 20g vitrectomy.Methods: The average time of surgery (33 min for 23g Vs 44 min for 20g vitrectomy) andpercentage of recovered vision at one week after surgery (83% for 23g Vs 43% for 20gvitrectomy) was used to calculate both effectiveness and cost effectiveness.Results: The effectiveness of 23 g vitrectomy was 83.9% and cost effectiveness US$ 542compared to 68.7% and US$ 663 respectively with 20g vitrectomy. The savings was equal to 3cataract surgery in India.Conclusions: 23g vitrectomy is more cost effective even in developing countries.
