Abstract
Background: Age related cataract is one of the commonest causes of diminution of vision worldwide.
Phacoemulsification is one of the most common surgical procedures in the world 1
. Changes in arterial blood
pressure, position of blood vessels, venous return of blood and CO2 levels all influence eye perfusion during cataract
surgery. The exact impact of phacoemulsification on macular perfusion is unknown 2&3
.
Purpose: To investigate the changes of macular perfusion parameters after uncomplicated phacoemulsification
using an optical coherence tomography angiography (OCT-A).
Subjects and methods: Thirty eyes of 30 cataractous patients, who had uneventful phacoemulsification with
implantation of IOL in the bag, were enrolled in this cohort study.
Participants underwent a complete ophthalmologic assessment and measurement of macular perfusion parameters
using optical coherence tomography angiography preoperatively and one week, one month, and three months
postoperatively.
Results: There was statistically significant increase in the level of parafoveal retinal thickness and perifoveal retinal
thickness in postoperative visits than preoperative visits. We have also found statistically significant increase in the
level of grid central vessel density in both superficial and deep capillary plexuses in postoperative visits than
preoperative visits.
Conclusion: Phacoemulsification positively increases retinal thickness particularly at parafovea and increases
vascularity in the center of fovea which makes phacoemulsification beneficial even beyond visual restoration.
