A Clinical Study on Phacoemulsification and Small Incision Cataract Surgery: Technique, Advantage and Disadvantage

Background:CATARACT which literally means “water-fall” is a leading cause of avoidable blindness worldwide, with 66% occurring in developing countries alone. Cataract amounts to about 81% of the total blindness (Govt. of India 1992) but a recent study shows that it may be around 65%. Cataract surger...

Description
Summary:Background:CATARACT which literally means “water-fall” is a leading cause of avoidable blindness worldwide, with 66% occurring in developing countries alone. Cataract amounts to about 81% of the total blindness (Govt. of India 1992) but a recent study shows that it may be around 65%. Cataract surgery has come a long way from Sushruta’s days of Couching to present day of Sutureless surgeries of Small Incision Cataract Surgery and PhacoEmulsification. With this there is a paradigm shift of opinion from just removal of cataractous lens to achieve a better unaided visual acuity with rapid postsurgical recovery and minimal surgery related complications.Aims and Objective:To study the techniques, advantages and disadvantages of MSICS and Phacoemulsification.Materials and Methods:This is a hospital based study of 40 patients with cataract attending the out-patient department and admitted at the Regional Institution of Ophthalmology, Minto Ophthalmic Hospital during April-2004 to December-2005. These cases were studied in respect of age, sex, duration of symptoms, medical history, preoperative astigmatism, management, response to management in terms of visual acuity, postoperative astigmatism and any other complications.Inclusion criteria:All patients with cataract admitted at Minto Regional Institution of Ophthalmology.Exclusion criteria:None.Results:Of the 40 patients, 20 each were operated by Phacoemulsification and MSICS respectively. 10 patients were operated via STI and SI. The surgically-induced astigmatism (SIA) noted was 0.975D +/-0.52D and 1.025D for Phacoemulsification and MSICS respectively with 6.0mm incision for both the surgeries. Comparing STI and SI the SIA was 0.76D and 1.2D respectively.Interpretations and Conclusions:The Surgically Induced Astigmatism (SIA) with Phacoemulsification and MSICS was statistically not significant when the incision was of the same size i.e. 6.0mm. But the SIA when the site of incision was superotemporal and superior though clinical significant did not have any statistical difference (due to limited amount of available data observations, the results need to be confirmed by a larger Community based study).
