Abstract
Introduction: Any opacity of lens and its capsule, whether developmental or acquired is called cataract. SICS has almost all the advantages of phacoemulsification and at the same time it is of reasonable cost as conventional ECCE with posterior chamber intraocular lens implantation. SICS can be done through superior or temporal approach.
Materials and Methods: Study was done on 80 patients selected from the patient admitted to indoor ward of RIMS, Ranchi, Jharkhand from December 2013 to July 2014. 40 patients underwent superior & 40 cases temporal small incision cataract surgery with IOL implantation. 80 eyes of patients were randomly allocated in four groups.
Results: In the present study, all patients of group 1 (superior – linear) had post-operative astigmatism whereas 85% patients of group 3 (Temporal – linear) had post-operative astigmatism. In group 2 (Superior – Frown), all patients had post-operative astigmatism while in group 4 (Temporal – Frown), only 85% patients had post-operative astigmatism. Frown incision group had shown less mean induced astigmatism as compared to linear incision group.
Conclusion: Cataract surgery continues to be evolutionary. Post-operative astigmatism is one of the most important factors which binders attainment of near normal unaided visual acuity following intraocular lens implantation.
