Abstract Details

Purpose:

Multifocal IOLs resulted in higher intraocular aberrations (HOA) and thereby could affect optical image quality. Newly launched Hanita Full Range IOL has better optical design. Hence the purpose is to compare visual outcomes and optical Image quality metrics in eyes implanted with Full range IOL versus monofocal IOL.

Setting:

Isha Netralaya, Kalyan, Maharashtra, India

Methods:

It was a prospective study design. Subjects implanted with Full range IOL (Hanita SeeLens) and monofocal IOL (Tecnis, ZCB00) were enrolled in the study. Subjects with cataract grade NS I-III, aged between 40-75 years, pre operative best corrected visual acuity 6/12 or worse, corneal astigmatism <1.00D were included in the study. Subjects with corneal pathologies, previous refractive surgery, glaucoma, retinal pathology, intra-operative complications were excluded. Post operatively 1 month ±7 days, uncorrected distance, near and intermediate visual acuities, internal higher order aberrations (HOA) for 4 mm pupil and modulation transfer function (MTF) by HOYA i-Trace aberrometer were measured and compared.

Results:

Thirty seven and 20 eyes were implanted with Full range and monofocal IOL with mean± SD age of 53.92±8.10 and 63.55± 4.89 respectively. Chi square test revealed that uncorrected distance visual acuities were similar (p=0.19) in both the IOLs however uncorrected near and intermediate visual acuities were significantly different (p<0.001). Two sample t test revealed no statistically significant difference in internal HOA (p>0.05) among both IOLs except spherical aberrations (p<0.01) which was significantly different. MTF were similar with both the IOLs.

Conclusions:

We noted similar intraocular HOA in eye implanted with Full Range and Monofocal IOL. This could be attributed to the superior design of the full range IOL however needs to be confirmed with larger sample size.
