Abstract Details



Purpose:

To report 1, 3, 6 and 12 month postoperative safety and effectiveness outcomes after monocular Presbia Microlens implantation for the improvement in uncorrected near vision in patients with presbyopia.

Setting:

Retrospective case series in a commercial setting in Ireland.

Methods:

Patients between 40 and 65 years of age were evaluated for tolerance to monovision, and if accepting of monovision, scheduled for corneal inlay implantation in the non-dominant eye. 60 patients were natural emmetropic presbyopes; 21 patients underwent concurrent LASIK and corneal inlay implantation. In all cases, the inlay was implanted in pockets created using a femtosecond laser at a depth of approximately 300 ┬Ám. Pre- and post-operative examinations of visual acuity for uncorrected and best corrected, near (UCVA-near, BCVA-near) and distance (UCVA-distance, BCVA- distance), using Snellen chart at 6m for distance acuity and EDTRS at 40cm for near, and manifest refraction were assessed. Additional examinations were performed (e.g., intraocular pressure, slit lamp). Subjective assessment of outcomes was solicited from patients during postoperative visits. Average postoperative follow-up was through 3 months.

Results:

No intraoperative complications were reported. 7.5% (6/81) of patients experienced adverse event of haze occurring after or persisting beyond 3 months. At the time of analysis only 1 of these (1.25%) was still under management, the others achieving resolution with topical steroid regimen. 2.4% (2/81) of patients underwent inlay explantation due to glare and non-adaptation (1 each). There were no reports of central visual field defect. Mean preoperative UCVA-near for all patients was LogMAR 0.78 (20/120) while at 3 months postoperatively, the mean was LogMAR 0.28 (20/38). The mean preoperative UCVA-distance for all patients was 20/20 at 3 months postoperatively, the mean was 20/40+. A mean of 20/20- for binocular UCVA-distance was achieved by all patients at 3 months postoperatively. 80% (36/45) at 3 months and 83% (24/29) at 6 months of patients expressed excellent or good UCVA- near postoperatively. 91.4% (33/36) of patients at 3 months and 93% (26/28) of patients at 6 months expressed no use of reading glasses post-operatively.

Conclusions:

The Presbia Microlens provided patients in this this study with a safe and effective method of improving near vision associated with presbyopia. As with all presbyopic treatments, diligence in patient selection and counselling is key to the success of the Presbia Microlens.
