Comparative evaluation of dry eye before and after manual small incision cataract surgery
Journal Title: Medpulse International Journal of Ophthalmology - Year 2017, Vol 4, Issue 2
Abstract
Background: Dry eye is a multifactorial disease of the tears and ocular surface that results in symptoms of discomfort, visual disturbance and tears film instability with potential damage to the ocular surface. It is accompanied by increased osmolarity of the tear film and inflammation of the ocular surface1. Many changes are observed in the eye after cataract surgery, one of them being onset of dry eye or change in the status of pre-existing dry eye. Thus inspite of a perfect cataract surgery and a good snellen visual acuity the patients may remain dissatisfied.Aims and objectives: To evaluate the proportion of dry eye before and after manual small incision cataract surgery. To assess the severity of dry eye symptoms using Ocular Surface Disease Index (OSDI) scores. To evaluate changes in tear secretion using Schirmer’s test 1(ST-1). To evaluate changes in tear film stability using tear film break up time (TBUT). Materials and Methods: Thestudy was a Quasi experimental study conducted on 110 eyes of 110 patients. The study was conducted for a period of 18 months. Complete ocular surface examination was done which included questionnaire using OSDI, Schirmer test – I,and tear film break up time which weremeasured in all the patients on the preoperative day and after 1 week, 3 weeks and 6weeks post operatively. Results: All the dry eye tests conducted on the eyes undergoing cataract surgery showed deterioration following surgery. All the parameters peaked at 3 weeks post operatively. Conclusion: Cataract surgery can lead to or aggravate dry eye disease. All the patients should be evaluated before and after SICS to prevent and manage dry eye effectively so that the patient will not have poor quality of life and vision due to dry eye disease.
