Abstract Details

Purpose:

To report the visual and refractive outcomes following monocular implantation of a small aperture IOL in eyes with previous laser vision correction.

Setting:

The study was undertaken in University Hospital Ayr, a district general hospital within the southwest of Scotland, United Kingdom.

Methods:

Prospective interventional case series. 11 eyes of 11 subjects with history of corneal laser vision correction were included. The small aperture IOL was implanted in the non-dominant eye while an aspheric monofocal IOL was implanted in the dominant eye. The dominant eye was aimed for emmetropia while the non-dominant eye was aimed for mild myopia(0.75 D). The ASCRS post refractive surgery online calculator was used for IOL power calculation. An experienced optometrist performed all the postoperative manifest refraction at week 4 for all subjects. All subjects were reviewed at day 1, week 1, 4 and 3 and 6 months postoperatively.

Results:

There were no intra-operative or post operative complications. The mean uncorrected distance visual acuity improved from 20/100 preoperatively to 20/25 post operatively in the non dominant eye and from 20/100 to 20/30 in the dominant eye. In the eyes with the small aperture IOL the mean uncorrected intermediate and near visual acuity improved from 20/100 to 20/25.

Conclusions:

Unilateral implantation of a small aperture IOL seems to be a safe and effective option in achieving spectacle independence following cataract surgery in eyes with prior laser vision correction. Aiming for mild myopia in the non dominant eye enhances the uncorrected intermediate and near vision without compromising on the distance visual acuity.
