Abstract Details

Purpose:

To evaluate the posterior segment visualization in patients with small – aperture intraocular lens (IOL).

Setting:

University Hospital Ayr, Ayr, Scotland, UK

Methods:

Prospective, comparative case series. Ten subjects who had unilateral implantation of the small – aperture IOL in their non-dominant eyes were recruited. Their fellow eyes were pseudophakic in nine subjects with a monofocal IOL and phakic in one. All underwent bilateral posterior segment clinical investigations including fundus photography, threshold perimetry, optical coherence tomography (OCT) of the posterior pole including optic nerve head. The results from these investigations were graded by a clinician masked to the laterality and the type of IOL. Subject number 11, developed post-operative endophthalmitis four weeks following cataract surgery with implantation of a small aperture IOL. He underwent pars plana vitrectomy. The intraoperative view of the posterior segment was subjectively evaluated by the retinal surgeon.

Results:

All 10 subjects had successful image capture with all the clinical investigative tools. The masked observer could not detect any difference in the image quality of these investigations between the monofocal pseudophakic and small aperture IOL eye. The small aperture IOL did not subjectively obstruct the intraoperative view for the retinal surgeon during pars plana vitrectomy.

Conclusions:

Standard posterior segment investigations including non mydriatic fundus photography, optical coherence tomography and automated perimetry can be safely and effectively performed in eyes in small aperture IOL. There is no difference in the image quality. Moreover, the small aperture does not seem to impede the intraoperative view during pars plana vitrectomy.
