Visual outcomes and higher-order aberrations in eyes implanted with hybrid extended depth of focus intraocular lens.

PURPOSE: To study the visual outcomes and higher order aberrations in eyes implanted with Hybrid EDOF IOL, particularly in Indian eyes.

MATERIALS AND

METHODS

This is retrospective case series where subjects aged between 40-65 years and were implanted with LUCIDIS IOL by single surgeon were included. Subjects with Pre surgery corneal astigmatism > 1.50 D, corneal guttae, IOP >22mmHg, any ocular Co morbidities, Intra or post operative complication were excluded. At 1 month follow up, uncorrected visual acuities at distance (UCDVA), intermediate (UCIVA) and near (UCNVA), refraction were recorded. Internal Higher order aberrations and strehl ratio for a fixed pupil of 4mm and 6mm were calculated using NIDEK OPD Scan. Monocular defocus curve was obtained at 4 meter logMAR chart.

RESULTS

Total of 55 eyes of 35 patients with mean±SD age of 58.50±7.49 years were evaluated. 89.09% of the eyes achieved visual acuity of 6/6. 49.09% could read N10 font at intermediate distance without any correction and 85.45% of the eyes had uncorrected near visual acuity of N6. Around 67% of the eyes did not require any refractive correction whereas around 26% of the eyes required correction upto ±0.25D. The defocus curve showed that visual acuity also ranges from 0.05 logMAR to 0.2 logMAR for Plano to -3.00D respectively. Mean±SD Strehl ratio at 4 and 6 mm pupil size was 0.06±0.04 and 0.02±0.02 respectively.

CONCLUSION

Hybrid EDOF IOL such as LUCIDIS provides excellent vision at all distances. This could be attributed to IOL design which is spherical aberration neutral lens.
