Abstract Details

Purpose:

Multifocal IOLs resulted in increased intraocular higher order aberrations (HOA) compared to monofocal IOL and thus could affect optical image quality. Hence, our purpose is to compare optical Image quality metrics in eyes implanted with multifocal (SeeLens Hanita) versus monofocal IOL (Tecnis ZCB00).

Setting:

Isha Netralaya, Kalyan, India

Methods:

It was a prospective comparative study where subjects implanted with multifocal IOL (SeeLens Hanita) and monofocal IOL (Tecnis ZCB00) as control group were enrolled. Subjects with cataract grade NS I-III, aged between 40-75 years, post operative best corrected visual acuity 0.2logMAR or better, corneal astigmatism <1.50D were included. Subjects with corneal and retinal pathologies, irregular astigmatism, previous refractive surgery, glaucoma, intra-operative complications were excluded. Post operatively 30±7 days, uncorrected distance, near and intermediate visual acuities, internal HOA and modulation transfer function (MTF) obtained using HOYA i-Trace aberrometer for 4 mm fixed pupil were recorded and compared among two groups.

Results:

Eighty eight and 20 eyes were implanted with Hanita and Monofocal Tecnis IOL respectively. The mean± SD age in multifocal Hanita and Monofocal Tecnis IOL group was 58.62±8.10 and 62.55± 4.89 respectively. Chi square test was used to analyzed uncorrected distance visual acuities which 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. MTF were similar at all spatial frequencies (5, 10, 15, 20, 25, 30 cycles per degree) with both the IOLs (p>0.05).

Conclusions:

We noted similar intraocular HOA and MTF in eyes implanted with multifocal and Monofocal IOL. However multifocal IOL has an advantage of providing intermediate and near visual acuity.
