A comparative study of superior scleral tunnel versus superior clear corneal phacoemulsification for senile cataract
Journal Title: Medpulse International Journal of Ophthalmology - Year 2018, Vol 8, Issue 1
Abstract
Background: Cataract is one of the common cause of reversible causes of visual impairment specially in older population. Cataract surgery has been evolving since many decades and phacoemulsification as described by Kelman has emerged the surgery of choice for cataract. It has the distinct advantage of better patient compliance, early stabilization of refraction, and better improvement in visual acuity. The two commonly used techniques of phacoemulsification are by clear corneal incision and phacoemulsification by scleral tunnel incision. We conducted this study to assess the merits and demerits of clear corneal incision in comparison with scleral tunnel incision in cases of cataract treated by phacoemulsification. Materials and Methods: This was a prospective interventional study conducted in the ophthalmology department of a tertiary care medical college situated ina rural area. The patients who presented with senile cataract to ophthalmology outpatient department during study period were included in this study on the basis of a predefined inclusion and exclusion criteria. Patients were divided into two groups: those to undergo Superior scleral tunnel (group A) and Superior clear corneal (group B) phacoemulsification followed by (Foldable) IOL implantation. Statistical analysis was done by using descriptive and inferential statistics, SIA calculator version 2.1 by Dr. Sawhney and Dr.Aggarwaland online calculator Social Science Statistics.Results: The overall study population consisted of 29.76% Females and 70.24% males in the present study. The most common affected age group was 61-70 years (52.38%) followed by 51-60 years (38.10) and 71-80 years (9.52%). In group A 6/6-6/9 uncorrected and best corrected visual acuity was found in 22 (52.38%) and 39 (92.86%) patients respectively; Similarly in group B they were 28 (66.67%) and 41(97.62%) patients respectively.Mean value of postoperative astigmatism in group A and group B was 0.86 ± 0.59 and 0.65 ±0.47 respectively. Most common type of postoperative astigmatismwas found to be against the rule astigmatism which was seen in 29 (69.05%) and 26 (61.90%) patientsin group A and group B respectively.There were no major complications seen in any of the group where as the most common minor complication in group A and Group B was found to be Striate keratopathy (23.81%) and corneal edema (16.67%) respectively. Conclusion: Phacoemulsification is the surgery of choice for cataract and is preferred by majority of the ophthalmologists for early stabilization and better visual outcome. Clear corneal phacoemulsification as well as Scleral tunnel incision both procedures have found to have comparable results as far as surgically induced astigmatism is concerned.
