INTRODUCTION: The use of the intraocular lens implant has been the most exciting development in ophthalmology of the last quarter century. So, during the past 2 decades the advances in cataract surgery have produced better visual outcome. Improvement by means of shortened healing time, a less cunbersome post-operative period, reduced chances of complication and a more predictable outcome. This demand for improvement can be satisfied by universal application of small incision surgery which allows faster and safer healing and reduced suture induced astigmatism. Two principal surgical techniques are used. 1. Phacoemulsification and posterior chamber intraocular lens implantation. 2. Manual Small incision sutureless cataract surgery with posterior chamber intraocular lens implantation. With an accurate estimation of the power of Intraocular lens, uncomplicated cataract surgery, and an uneventful post-operative period, the implant is capable of providing a visual acuity of 6/6. Hence, this study is an attempt of comparison of visual outcome in MSICS & Phacoemulsification of 100 cases at Govt.Rajaji Hospital, Madurai in relation to (1) Effectiveness which is shown by BCVA - in both the procedures (2) Safety in relation to the incidence of intraoperative complications - in both the procedures. AIMS AND OBJECTIVES: The aim is to compare the two cataract extraction procedures performed in 100 patients at Govt. Rajaji hospital, Madurai during the year 2005 January to 2005 December. 1. Manual Small incision sutureless cataract surgery with PCIOL implantataion (MSISCS /PC-IOL) 2. Phaco Emulsification with PC IOL implantation (PHACO/PC-IOL) In terms of a) Visual acuity b) Induced astigmatism c) Incidence of intra-operative complications. MATERIALS AND METHODS: Our study was a randomized prospective study of comparing the two cataract extraction procedures (MSICS/PC-IOL & Phaco Emulsification /PC-IOL) In terms of Visual acuity, Induced astigmatism, Incidence of intraoperative complications at Dept.of Ophthalmology, Govt. Rajaji Hospital, Madurai. SUMMARY: The aim of our study was to evaluate and compare the visual out come in the two cataract procedures ( manual phaco and instrumental phaco) Efficacy was determined by evaluating visual acuity outcome and surgically induced astigmatism.Safety was determined by assessing the incidence of intra- operative complications. CONCLUSION: In our study the visual outcomes were comparably the same in the 2 cataract procedures ( MSICS & PHACO) Phaco group produced slightly less mean induced astigmatism compared to the manual phaco The instrumental phaco group produced less serious complications than manual phaco. In Government institutions like ours (Government Rajaji Hospital), where there is a large group of population to be catered, we have to consider the economic constraints also Now with more training facilities, experienced surgeons, and with the availability of sophisticated instruments Phacoemulsification is done for selected cases only with less complications. In future, both manual and Instrumental phaco can be applied equally for all set up. This may also reduce the number of complication and follow up visits. Hence both are equally safe and effective in skilled hands to acquire better visual outcome.
