Objective visual quality one year after toric IOL implantation for correction of moderate and high corneal astigmatism
AIM: To compare the objective visual quality after implantation of a toric intraocular lens (IOL) in order to correct moderate or high corneal astigmatism at the one year postoperative follow-up. METHODS: From December 2017 to June 2018, 66 patients (90 eyes) with simple age-related cataract with re...

| description | AIM: To compare the objective visual quality after implantation of a toric intraocular lens (IOL) in order to correct moderate or high corneal astigmatism at the one year postoperative follow-up. METHODS: From December 2017 to June 2018, 66 patients (90 eyes) with simple age-related cataract with regular corneal astigmatism greater than 1.5 D were enrolled in this prospective self-control study. The patients were implanted with Proming® toric IOL (model: AT3BH-AT6BH). The subjects were divided into moderate astigmatism group (46 eyes, 1.5-2.5 D) and high astigmatism group (44 eyes, >2.5 D). The uncorrected distance visual acuity, residual astigmatism and axial position of IOL were observed before operation, 3, 6mo and 1y after operation. Modulation transfer function cutoff (MTF cutoff), Strehl ratio (SR), object scatter index (OSI) were observed by OQAS II to evaluate the objective visual quality of patients. RESULTS: There was no significant difference in UCVA, residual astigmatism, axial deviation, MTF cutoff, SR and OSI between moderate and high astigmatism group (all P>0.05). After 3mo, UCVA, MTF cutoff and SR were significantly increased (all P<0.05), residual astigmatism and OSI were significantly decreased (all P<0.05). After 3mo, all the indexes remained stable. CONCLUSION: Proming toric IOL can effectively treat age-related cataract patients with moderate-to-high regular corneal astigmatism, correcting corneal astigmatism, improving UCVA, ensuring long-term stability in the capsule, and providing patients with better visual quality. |
