Study of changes in macular thickness following uneventful cataract surgery

Abstract

Worldwide, cataract accounts 47.8%. Phacoemulsification cataract surgery had good results. Current study aimed to identify the macular thickness following uneventful phacoemulsification & small incision cataract surgery method (SICS) comparison with visual acuity. Materials and Methods: In total (n=50) patients, 50% undergone SICS for one eye with bag polymethacrylate intraocular lens implantation and 50% undergone phacoemulsification method in one eye with in bag acrylic type of foldable IOL. Postoperatively patients followed on day 7, week 2 and week 4 and upto 3 months. The complete ophthalmological examination and OCT of macula was done at follow-up. Results: Subclinical macular oedema noted in one case at 1 st , 2 nd and 4 th week follow-up, but it was reduced at 3 rd month. There was statistical (p<0.05) significant difference observed in macular thickness between the preoperative & post operative 1 st week, post-operative 2 nd week & post-operative 4 th week followup in Phaco group. Eyes with SICS procedure also shown statistical (p<0.05) significant difference as above pre and postoperative follow-ups without affecting the final visual outcome. Conclusion: Post operatively, there was increased macular thickness without affecting the final visual outcome following phacoemulsification procedure. Subclinical macular edema noted at 1 st week and reduced at 3 rd month.

Central macular thickness change after uneventful small-incision cataract surgery - An observational study

“…The mean surgical time was found to be 10.50 ± 1.66 minutes, which was comparable to that of the study conducted by Dr. Shaik Nasreen et al ,[ 22 ] quoting a mean surgical time of 9.8 ± 0.50 (9.5 to 10.2) minutes.…”

“…In the study conducted by Jagow B et al ,[ 23 ] Cagini et al ,[ 24 ] Sandeep K et al ,[ 25 ] and Nasreen et al ,[ 22 ] there was no correlation found between macular thickening and visual acuity.…”

Change in macular thickness after uncomplicated phacoemulsification surgery using optical coherence tomography in a tertiary care hospital

“…In our study, after uncomplicated phacoemulsification macular thickness increased from first week to 6th month as shown by OCT. Nasreen et al 13 conducted a similar study and observed that macular thickness showed an increasing trend after uncomplicated phacoemulsification starting from first week to 6th month which was also favored by a study conducted in 2021 by Kemer et al 14 A study conducted by Lobo et al 15 showed that increase in macular thickness was initially present in perifoveal region and then it leaked and accumulated in fovea. This was analyzed by retinal leakage analyzer (RLA) which demonstrated that primary site of leakages was perifoveal vascular structure.…”
