Abstract Details

Purpose:

To analyze the visual outcome after cataract surgery in patients with previous corneal refractive surgery.

Setting:

Cataract surgery clinics in 19 European countries. Database study.

Methods:

Cases of cataract extraction with previous corneal refractive surgery (refractive cases) were identified from all cataract extractions reported to the European Registry of Quality Outcomes for Cataract and Refractive Surgery database, over 5 years. Preoperative and postoperative measurements and trends over time were analyzed.

Results:

Twelve hundred and twenty-nine of 807,220 cataract extractions (0.15%) were refractive cases, with significant increase over time (p﹤0.001). Refractive cases were younger than non-refractive cases (62.9 years versus 74.0 years; p﹤0.001), but had similar mean preoperative and postoperative corrected-distance visual acuity (CDVA) (preoperative logMAR 0.44[6/16] for both [p=0.286]; postoperative logMAR 0.06[6/7] for both [p=0.245]). Postoperative CDVA was worse than preoperative CDVA in 35 (4%) refractive and 8,999 (1.5%) non-refractive cases (p﹤0.001). Seventy-four of 873[8.5%] refractive, versus 16,566 /584,496[2.8%] non-refractive patients, had preoperative CDVA of logMAR 0.0[6/6] or better (p﹤0.001).

Conclusions:

Cataract surgery has been reported with increasing frequency, in post-corneal refractive surgery patients, since 2008. These patients had similar preoperative CDVA to patients without prior corneal refractive surgery, but were younger and were at a higher risk of worse postoperative CDVA, especially if they had preoperative CDVA of logMAR 0.0(6/6) or better.
