Abstract Details

Purpose:

To assess initial clinical outcomes in cataract patients with corneal astigmatism implanted with aberration-neutral, hydrophobic acrylic monofocal toric (MX60T, Bausch & Lomb) intraocular lens (IOL) technology.

Setting:

Single-center, single-surgeon, prospective clinical case series

Methods:

A single-center, single-surgeon, prospective case series involving 70 eyes of 50 patients (20 bilateral) with age-related cataract and clinically significant corneal astigmatism treated with standard cataract extraction and implanted with the MX60T IOL.  Early patient outcomes at 1 week were analyzed and compared with preoperative parameters.  Clinical outcomes include: keratometry (K), best corrected distance visual acuity (BCDVA), uncorrected distance visual acuity (UCDVA), refractive cylinder (Cyl), manifest spherical equivalent (MRSE), and safety (reposition).

Results:

Preoperative delta K, Cyl, and MRSE were 1.8±1.2D, -1.65D±1.3D, and -1.84±4.4D respectively.  Average BCDVA without glare was 0.2±0.17 logMAR.  At 1-week post-op, both cylinder and MRSE improved significantly (Cyl: -0.33±0.59D, p=0.0 and MRSE: -0.03±0.4D, p=0.4).  Average UCDVA was 0.06±0.14 logMAR with 79.3% of eyes seeing 20/25 or better.  One patient required repositioning and improved to 20/20 UCDVA with a 0.25D MRSE.

Conclusions:

Patients implanted with aberration-neutral monofocal toric IOL demonstrated excellent uncorrected distance visual acuity (0.06 logMAR) and an 80% reduction in refractive cylinder postoperatively.  Early results demonstrate good efficacy in correcting astigmatism in cataract patients with this new monofocal toric IOL platform.
