Comparative study of tear flim abnormalities and dry eye conditions in ocular surface following phacoemulsification and small incision cataract surgery [SICS] A hospital based prospective study

Abstract

To study ocular surface and tear flim abnormalities in patients undergoing [PHACO] and [SICS]. [DED] is a disease of either tears or the ocular surface which leads to visual disturbance. SICS resulting in corneal hyposensitivity and reduction in reflex secretion and wound healing. PHACO is a contemporary cataract surgery in which the eyes internal lens is emulsified and aspirated from the eye using an ultrasonic handpiece.A Hospital based prospective study involved 100 patients aged 40-65 years.100 patients were subdivided into 2 groups, 50 members in each group. The observation of TBUT before surgery and after 1,3,6 months post-surgery were carried out in both group of patients.In this study 100 patients were subdivided into 2 groups, 50 members in each group as follows Group 1-50 patients scheduled for SICS with PCIOL implantation, Group 2-50 patients scheduled for PHACO with PCIOL implantation. Preoperatively the mean Schrimer value was 13.70 and 13.40 in patients underwent SICS and PHACO respectively. At postoperative 1 week, 89.1% of the group had grade 2 dry eye compared to 92.9% in the SICS group [p 0.0001].Individuals with SICS had a higher prevalence and severity of dry eyes than those with PHACO.
