Extent of multifocality with corneal manipulation in manual small incision cataract surgery with monofocal posterior chamber intraocular lens implantation
Purpose: To compare the visual outcome in terms of multifocality in Manual Small Incision Cataract Surgery (MSICS) with and without intraoperative manipulation of corneal curvature. Methods: This was a prospective study on 80 subjects (80 eyes) who underwent MSICS with monofocal posterior chamber in...

| description | Purpose: To compare the visual outcome in terms of multifocality in Manual Small Incision Cataract Surgery (MSICS) with and without intraoperative manipulation of corneal curvature. Methods: This was a prospective study on 80 subjects (80 eyes) who underwent MSICS with monofocal posterior chamber intraocular lens (PCIOL) implantation between January 2018 and October 2019. Intraoperative manipulation of corneal curvature using viscoelastics was performed during MSICS in 40 subjects (cases) while this intraoperative manipulation was not performed in the remaining 40 subjects (controls). Uncorrected distance visual acuity (UDVA) and uncorrected near visual acuity (UNVA) were compared at day 1, 7, 30 and 180postoperatively. Results: At 1 month and 6 months of follow up, UDVA was comparable in the 2 groups. UNVA was better in cases than controls at 1 month and6 months (P < 0.001). At 6 months of follow up,76% of cases with UDVA of 6/9 or better had UNVA of N8 while only 15% of controls with UDVA of 6/9 or better had UNVA of N8 (P <0.001). Mean near add requirement to achieve a best corrected near vision (BCNV)of N6 at 6 months was significantly lesser (P =0.002) in cases (+2.05 D) compared to controls (+2.43D). Conclusion: MSICS with intra operative manipulation of corneal curvature resulted in better unaided near visual acuity compared to that without intra operative manipulation of corneal curvature, without compromising unaided distant visual acuity. |
