Abstract Details

Purpose:

To compare modulation transform function (MTF) between standard monofocal spherical hydrophobic acrylic Alcon SA60AT (Bausch & Lomb) and hydrophilic acrylic Rayner Superflex (620H, Rayner) IOLs.

Setting:

This cross sectional study was conducted on 68 patients who underwent cataract surgery at Noor Eye hospital, Tehran, Iran.

Methods:

The hydrophobic Alcon SA60AT IOL was implanted in 39 and the hydrophilic Rayner Superflex (620H) was implanted in 29 eyes. The far best corrected visual acuity of the participants was 20/20. The OPD Scan III (Nidek) was used to assess MTF in normal pupils under mesopic light conditions 1 and 3 months after the surgery.

Results:

T-test showed no significant difference in mean MTF between the two IOLs in the 2 follow-ups (p=0.788). The results of repeated measure ANOVA for each type of IOL indicated that MTF increased significantly in the hydrophilic group versus the hydrophobic group in the third month (p=0.033). Moreover, the results of repeated measure ANOVA showed that MTF was affected by the type of IOL and refractive error in the 3rd month (p=0.029, p=0.025).

Conclusions:

It seems that the material of IOL and post surgical residual refractive error can affect the visual acuity of pseudophakic patients. Although the hydrophilic IOL provided a better MTF three months after the surgery, studies with longer follow-ups are required to confirm the results.
