Trifocal IOL in highly myopic eyes achieves satisfactory outcomes

Patients with highly myopic eyes who received a trifocal IOL achieved satisfactory refractive and visual outcomes, but the outcomes were not as favorable in eyes with low IOL power compared with higher dioptric IOL power, according to a study.
The retrospective case series included 18 eyes of 10 patients in the highly myopic group that had IOL power between 0 D and 10 D and 18 eyes of nine patients in the age-matched control group that had IOL power greater than 10 D. Researchers analyzed outcomes at 3 months, including uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA) and uncorrected near visual acuity (UNVA). Spherical equivalent and refractive astigmatism were analyzed as well.
At 3 months postoperatively, all eyes had spherical equivalent accuracy of ±1 D, but the UDVA and UIVA were significantly worse in the highly myopic eyes compared with the control eyes (P = .022 and P = .033, respectively). The difference in UNVA did not reach statistical significance.
The highly myopic group at 3 months postoperative had a mean UDVA of 0.06 logMAR, UIVA of 0.13 logMAR and UNVA of 0.12 logMAR, while the control group had a mean UDVA of –0.01 logMAR, UIVA of 0.04 logMAR and UNVA of 0.04 logMAR.
Corrected distance visual acuity was 0.1 logMAR or better in all eyes. – by Robert Linnehan
