Abstract Details

Purpose:

To investigate the objective results of refractive lens exchange in the treatment of patients with near-emmetropic-presbyopia using multifocal intraocular lenses.

Setting:

Optegra Eye Hospital Yorkshire, Bradford, UK

Methods:

Single surgeon (SR), single site, retrospective case review. We examined the visual and refractive outcome of 58 eyes in 29 patients who had undergone bilateral IOL implantation. Pre-operatively patients were emmetropic in both eyes and only admitted to wearing glasses for presbyopia. Pre-operative emmetropia was defined by a spherical equivalent between -0.75 D and +0.75 D. The mean age of the patients was 63.2 ± 8.5 years, ranging from 50 to 84 years. The following IOLs were implanted: segmented bifocal (34) and diffractive trifocal (24) and available data are reported.

Results:

Mean pre-operative UDVA and CDVA were 0.05 ± 0.12 logMAR (14 eyes) and 0.03 ± 0.14 logMAR (11 eyes), respectively. Post-operative results were as follows: Mean spherical equivalent -0.19 ± 0.39 D, ranging from -1.38 D to 0.75 D (42 eyes). Mean monocular UDVA 0.03 ± 0.11 logMAR (40 eyes). Monocular UNVA of N6 or better was achieved by 82 % (28 eyes) and monocular UIVA of N12 or better was achieved by 60 % (10 eyes). Mean binocular UDVA was -0.10 ± 0.06 logMAR (7 patients). No operative complications occurred.

Conclusions:

Refractive lens exchange in emmetropic-presbyopia patients can result in an acceptable standard of visual outcomes, preserving distance vision whilst simultaneously improving uncorrected near and intermediate visual acuity.
