A Clinical Study to Compare the Accuracy of Digital and Manual Marking for Toric IOL Alignment
Journal Title: International Journal of Contemporary Medical Research - Year 2017, Vol 4, Issue 1
Abstract
Introduction: Cataract surgery now a days is a refractive surgery. For cataract patients with regular astigmatism, toric IOL (Intraocular lens) provide the potential for better uncorrected visual acuity than they ever had. The prevalence of corneal astigmatism more than 1.5 dioptres (D) ranges between 15% and 30% as reported by different studies. The aim of the present study was to compare the clinical outcome of digital and manual marking for toric IOL alignment. Material and Methods: The present study is randomized controlled trial study carried out at tertiary eye care hospital at Bareilly to find out residual astigmatism in patients in whom toric IOL were implanted in period from January 2016 – December 2016. Outcome measures: The best corrected visual acuity along with residual astigmatism was noted. Degree of rotation of IOL postoperatively was also noted. Results: During our study, there was no statistical difference between the two marking techniques and both of them induced almost similar amount of error. Conclusion: We found in our study that both the marking techniques produced almost similar results. Instead of going for newer techniques which are very costly these techniques produce comparable results.
