Purpose

To outline the early postoperative objective visual and refractive outcomes and subjective quality of vision (QoV) following implantation of a new refractive partial range of field extended intraocular lens (IOL) in eyes with a history of previous hyperopic or myopic refractive laser surgery.

Setting

Cathedral Eye Clinic, Belfast, Northern Ireland, UK

Methods

The study enrolled 18 patients (33 eyes) with previous hyperopic refractive laser surgery (Group A) and 13 patients (23 eyes) with previous myopic surgery (group B). Eyes underwent RLE or cataract surgery with implantation of the Tecnis PureSee IOL (Johnson & Johnson). The first myopic target was selected in the first operated eye (dominant eye) with a micro-monovision offset up to -0.70 D selected for the second eye. Uncorrected distance (UDVA), intermediate (UIVA) and near (UNVA) visual acuities, refractive error, and quality of vision (QoV) were measured 3 months postoperatively.  

 

Results

Mean binocular UDVA was -0.01±0.11logMAR in group A and -0.05±0.09logMAR in Group B. Mean binocular UNVA was 0.20±0.11 and 0.22±0.10logMAR, and UIVA was 0.09±0.10 and 0.09±0.06 logMAR in the respective groups. Postoperatively, 63.6% and 100% were within ±0.50D and ±1.00D of the refractive target in group A, and 78.3% within ±0.50D and 91.3% within ±1.00D in group B. Monocular defocus curves displayed mean visual acuity better than 0.20logMAR from +1.0D and to approximately -1.8D defocus in group A and from +1.0D to approximately -2.0D in group B. Mean day and night QoV scores of 8.4 ± 0.84 and 7.8 ± 1.23  were reported in group A and 9.0±0.71 and 8.11±1.45 in group B with minimal dysphotopsias and high rates of spectacle independence.

Conclusions

This new refractive partial range of field extended IOL provides a satisfactory range of vision with minimal visual side effects and high patient satisfaction in eyes with both previous hyperopic and myopic laser refractive surgery. Further data with longer-term follow-up will be presented at the conference.
