Quantitative Changes

The clinical evaluation of macular edema has been difficult to characterize, but evaluation has become more precise with the help of optical coherence tomography (OCT). This study is undertaken to evaluate the quantitative changes in macular thickness using spectral domain OCT in diabetic patients undergoing cataract surgery pre and post operatively and its relation with diabetic retinopathy (DR). Study participants included 65 diabetic patients irrespective of presence or absence of retinopathy who underwent cataract surgery. Each eye underwent fundus examination with indirect ophthalmoscopy and OCT of macula i.e.,preoperatively and at postoperatively at day 1, 1 week, 4 weeks and at 12 weeks. Best-corrected visual acuity (BCVA) was recorded at each visit. The central subfield macular thickness (CSMT) increased in all patients irrespective of presence or absence of diabetic retinopathy of about 17.4±25.3µm and 29µm±38.8 at 1 month and 3 month follow up. There was a statistically significant increase seen in CSMT after cataract surgery especially in patients with preoperatively diagnosed macular edema. Associated retinopathy also acts as a risk factor. But there was no statistically significant increase in mild and moderate NPDR preoperatively and also in postoperative period after uncomplicated small incision cataract surgery.

Background: This study aims to assess dry eye indices following cataract surgery. Materials and Methods:  A single center descriptive and comparative study was performed. A total of 100 eyes of 100 cases fulfilling the inclusion criteria from 1st June 2017 to 30th May 2018 were enrolled. Out of 100 eyes, 50 eyes each went through manual small incision cataract surgery (MSICS) and phacoemulsification respectively. For objective analysis : schirmer 1 test(ST-I), tear breakup Time(TBUT) along with lissamine Green Surface Staining(LGSS) was performed on pre-operative day, 1st, 4th and 12th week respectively. Ocular Surface Disease Index (OSDI) was done for subjective analysis on pre-operative day and at 12th week. Results: The mean age of the patient was 53.66 ± 7.839 years with 34 (68%) being female in a small incision cataract surgery group.  In the phacoemulsification group, mean age was 54.72 ± 7.985 years and 32 (64%) were female.  On analyzing the objective dry eye indices: ST-I,TBUT and  LGSS at 12thweek was 18.80 ± 7.393 mm, 11.30 ± 5.456 seconds and 1.62 ± 1.193 in Small incision cataract surgery group and 27.10 ± 6.326 mm, 16.60 ± 4.699 seconds and 0.38 ± 0.602 in Phacoemulsification group respectively which was statistically significant. (p< 0.001).  Conclusion: Regardless of the type of cataract surgery, dry eye disease is unavoidable affecting both tear quality and quantity postoperatively. In our study, phacoemulsification had lesser effect in dry eye indices than small incision cataract surgery.
