Publication Comparison of preoperative and postoperative corneal astigmatism after phacoemulsification through a 2.8mm clear corneal temporal incision(Institute of Medicine, 2016) Joshi, SN; Pant, M; Rijal, S; Bhattarai, DAbstract Introduction: Phacoemulsification with foldable intraocular lens implantation through clear corneal incision has become common surgical approach for cataract surgery because it produces minimal surgically induced astigmatism and provides best postoperative visual acuity. This study thus aims to compare the preoperative and postoperative corneal astigmatism and to compare the postoperative change in keratometric astigmatism between right and left eyes after temporal 2.8 mm clear corneal incision phacoemulsification cataract surgery and implantation of foldable intraocular lenses. Methods: A prospective study included 31 patients with bilateral senile cataract who had undergone sutureless, 2.8mm clear corneal incision phacoemulsification cataract surgery with foldable intraocular lens implantation. Keratometry was recorded preoperatively and weeks postoperatively using Nidek automated keratometry. A paired sample t-test was performed to compare the preoperative and postoperative corneal astigmatism. Results: Mean age of the population was 63.39 plus/minus 9.705 years (range: 49 to 83 years). Before surgery, mean corneal astigmatism in right and left eye was 0.92 plus/minus 0.58 * D and 0.85 plus/minus 0.61 * D respectively. After the surgery, mean astigmatism in right eye was 0.97 plus/minus 0.51 * D and in left eye was 0.97 plus/minus 0.48 * D There was no statistically significant difference in preoperative and postoperative keratometric astigmatism of both eyes. (RE: p-valve 0.427; LE: p-valve 0.188) Conclusion: Temporal clear corneal incision is quite stable and has minimal effect to corneal astigmatism.

Both the procedures have been approved by World Health Organization for use in early first trimester. Objectives The study aims to compare efficacy and safety of medical abortion with surgical abortion in a district hospital of rural eastern Nepal. Method An observational study conducted in district hospital, dhankuta from July 2010 to January 2011. Clients for abortion services were counseled about methods of abortion and were allowed to make decision on their own and classified as medical abortion group (N=48) (receiving 200milligram Mifepristone followed by 800 microgram misoprostol sublingually or vaginally on day two)and manual vacuum aspiration group (N=36). The two groups were compared for rate of complete abortion and other complications and contraception use after procedure. Results Rate of complete abortion was similar in both groups, 95.8% among medical abortion and 97.2% in manual vacuum aspiration. Moderate to severe expulsion bleeding was reported in 91.6% of cases after Medical Abortion but none required medical attention for hemorrhage. Condom was the most preferred contraceptive in medical abortion group and depo provera in manual vacuum aspiration group. Conclusion Medical method of abortion using mifepristone and misoprostol is equally safe and effective as manual vacuum aspiration in rural setting district hospitals of Nepal.

Till date no study has been reported about use of contact lenses for these purposes in Nepalese population. is study thus aims to evaluate the outcome of TCL in ocular surface disorders in Nepalese population. Methods: A prospective analysis of patients fitted with TCL for various ocular surface disorders was done at B.P. Koirala Lions centre for Ophthalmic Studies. All the subjects were fitted with Poly-2-hydroxy ethyl methacrylate (70% water content); information on clinical conditions were evaluated and recorded at initial and final treatment visit. Results: Of 57 eyes fitted with TCL, corneal laceration caused by mechanical injury (22.8%) and vernal keratoconjunctivitis (21.1%) were the most common ocular surface disorders. The common indications for applying TCLs were to alleviate pain and discomfort (31.5%) and corneal thinning impending to perforation (26.3%). Subjects’ clinical conditions and symptoms were resolved partially to completely in 89.4%. Dry eye was a common cause of contact lens associated therapeutic failure. Conclusion: Poly-2-hydroxy ethyl methacrylate contact lenses are safe and effective in alleviating symptoms and healing of various ocular surface disorders in Nepalese population.
