Purpose
To evaluate refractive and visual outcomes of single-piece aspheric aberration neutral hydrophobic monofocal toric intraocular lens (IOL) in cataract patients with corneal astigmatism.
Methods
Prospective, single-site, single-surgeon, case series on spherical aberration neutral monofocal toric IOL (enVista MX60T, Bausch and Lomb, Inc). A total of 29 eyes (n=25, 4 bilateral) were included in this study. Study parameters included: Pre-op MRSE, pre-op delta K, Post-op visual acuities at distance, intermediate, and near, post-op manifest refraction, BCDVA, refractive prediction error, and absolute IOL rotation at 1 day and 1 month.
Results
Average pre-op MRSE was -0.87D (±3.58) with average cylinder of 1.57D (±0.87D). Post-op at 1M, MRSE improved to -0.41D (±-0.51D) with cylinder of 0.19D (±0.23D). Most eyes (≥91%) achieved MRSE of ±0.50D from predicted and all eyes showed ≤0.75D of refractive cylinder. At 1M, 91% of eyes had 20/25 or better visual acuity at distance and 87% of eyes achieved the same acuity level at intermediate. Average near acuity was J2.5 with 83% of eyes seeing J3 or better. All eyes were rotationally stable with 100% showing ≤5° rotation from surgery to 1 day and 1 month. No complications were observed post-operatively.
Conclusion
In this prospective case series, EnVista Toric IOL was predictable, rotationally stable, and effective in reducing refractive astigmatism. The aberration free optic appeared to improve range of vision while maintaining image quality.
