Efficacy of SRKT biometry formula

To evaluate the predictive accuracy of SRKT formula in biometry. Two hundred eyes which underwent cataract extraction by phacoemulsification and implantation of a posterior-chamber intraocular lens were included in the study. Depending upon the axial length the patients were divided in four groups. Group-l: Axial length<22 mm, n=28 eyes [14%].Group-2: Axial Length 22.00-24.5 mm, n=136 [68%]. Group-3: Axial Length 24.6-26 mm, n=25 eyes [12.5%]. Group-4: Axial Length > 26 mm, n=11 eyes [5.5%]. In all patients SRKT formula was used to calculate the power of intraocular lens. Group-I: The mean deviation in refraction was 0.42D with SRKT and 0.56D with RCOphth guidelines. Group-2: The mean deviation in refraction was 0.62D with SRKT and 0.59D with RCO guidelines. Group-3: The mean deviation in refraction was 0.43D with SRKT and 0.41D with RCOphth guidelines. Group-4: The mean deviation in refraction was 0.42D with SRKT [RCOphth recommends the same formula for this length of eye ball]. When the overall mean deviation [of all four groups] was calculated, it was 0.56D for SRKT [range 0 to 2.81D] and was 0.52 D if RCOphth guidelines had been followed. Postoperative BCVA of 6/12 or better was achieved in 197 eyes [98%]. SRKT formula performed credibly in average-length eyes as well as in the long eyes. For short eyes results would have been better if Hoffer Q formula had been used

Fungal keratitis; role of topical miconazole in management

Previously no topical antifungal was available and only dermatological preparation like bifonazole [mycospore] and some systemic antifungal were used for treatment of fungal ulcers. Now miconazole is available as topical ophthalmic ointment for the management of fungal ulcer. To Study the efficacy of topical miconazole ophthalmic ointment in the management of fungal keratitis and to know the time period required for complete healing with topical miconazole ophthalmic ointment. Department of Ophthalmology, Nishtar Hospital, Multan. One year [from March 2001 to February 2002]. Sample size: 20 patients. According to this study of 20 cases it is apparent that the fungal keratitis occurred most frequently in patients between 20-70 years of age. It is apparent those males who work at different places are more prone to disease. Out of 20 cases, 10 [50%] were farmers by occupation. Trauma with fingernail in 1[5%] patient, trauma with ston e in 2[10%] patients. No specific eye disease was present in 12[60%] cases. Trachoma was present in 4[20%] cases. Blephritis was diagnosed in 2[10%] cases, 2[10%] patients were suffering from chronic illness like chest infection. Fungal keratitis in 12[60%] was not associated with hypopyon, 6[30%] patients were associated with hypopyon and 2[10%] were associated with end-ophthalmitis. The response was good in 12[60%] patients and satisfactory in 3[15%]. Poor response in 3[15%] and there was no response in 2[10%] cases. Miconazole ophthalmic ointment is a good drug for the treatment of fungal keratitis
