BACKGROUND: To investigate the outcomes of bilateral implantation of enhanced monofocal intraocular lenses (IOLs, ICB00) with a - 2.00 diopter (D) target in patients with moderate to high myopia and to compare the clinical outcomes of a - 2.00 D binocular target with an emmetropia target in patients who underwent cataract surgery.
METHODS: In this retrospective study, we reviewed the medical records of patients who underwent uncomplicated phacoemulsification with ICB00 IOL implantation. Emmetropia (Group 1) and - 2.00 D (Group 2) were targeted in 60 and 20 eyes of 30 and 10 patients, respectively. Three months after surgery, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), and uncorrected near visual acuity (UNVA) were measured. Defocus curves were measured under the photopic condition by intervals of 0.50 D from + 0.50 D to - 4.00 D.
RESULTS: The postoperative binocular logMAR UDVA, UIVA, and UNVA were 0.01 ± 0.03, 0.08 ± 0.11, and 0.33 ± 0.15 in Group 1 and 0.31 ± 0.13, 0.04 ± 0.05, and 0.11 ± 0.07 in Group 2, respectively. Group 2 showed a significantly superior postoperative binocular UNVA (P = 0.027) and inferior binocular UDVA (P = 0.003) than Group 1. Binocular UIVA and CDVA did not significantly differ between the groups although UIVA was better in Group 2 than in Group 1. Near glasses were needed by 66% of Group 1 and 0% of Group 2.
CONCLUSIONS: Bilateral implantation of ICB00 IOL with - 2.00 D of residual myopia is suitable for patients with moderate to high myopia to improve UDVA, UIVA, and UNVA.
