Abstract Details

Purpose:

To demonstrate the safe use of a multifocal IOL in patients who have previously had corneal laser vision correction surgery. Patient selection, surgical technique and IOL choice are discussed. The potential optical benefits of a rotationally asymetric refractive EDOF lens in this application are discussed.

Setting:

Prospective case series. Single surgeon, Private refractive/ cataract surgery practice. Vision Eye Institute - Bondi Junction, Sydney University of NSW

Methods:

Patients presenting with cataract (who have previously had laser vision correction surgery) were operated and implanted with an Oculentis Comfort ( MF15, MF20) toric and non toric IOLs. Patients were selected based on motivation, corneal regularity, Visual axis and aberration pattern. Outcomes were assessed with UCVA for distance, intermediate and near, Objective Glare and Halo measurement, and a subjective questionnaire.

Results:

20 eyes were implanted in 10 patients with minimum 3 month follow up. There were no surgical complications. UCVA at 3 months; 90% 6/7.5 or better DVA, 72% N5 or better NVA, 72% N5 or better Intermediate VA. All patients had 6/7.5 and N6 binocularly unaided. Glare and Halo testing demonstrated an absence of haloes in night driving and minimal glare with the low near add IOL. Subjective visual function score of 92 (out of 100), compared with conventional diffractive multifocal IOLs (in non lasik eyes) that typically score between 85 and 90. One patient may come to IOL exchange.

Conclusions:

It is possible and safe to use a presbyopia correcting IOL in post lasik patients. These patients are motivated to achieve spectacle independence having had lasik before the onset of presbyopia. The Oculentis low near add EDOF lens may be a good choice for post lasik patients. The refractive segmental platform is more tolerant of corneal irregularity and as an EDOF lens, patients achieve a functional range of vision without the halo problem seen with diffractive IOLs . Accurate refractive outcomes are critical and care should be taken in patient with significant corneal irreguarity.
