Background

High astigmatism remains challenging in keratorefractive lenticule extraction because small errors in centration or cyclotorsion may affect astigmatic correction.

Purpose

This study evaluated early refractive and astigmatic vector outcomes after small-incision lenticule extraction (small-incision lenticule extraction) Pro using the VISUMAX 800 in eyes with high astigmatism.

Methods

This prospective interventional cohort study was conducted at Cung Hong Son International Eye Hospital, Hanoi, Vietnam.

n = 160 eyes
Results

nearly all eyes had astigmatism-related distortion corrected to within a safe, mild range

69%
≤0.50 D residual cylin
98%
≤1.00 D residual cylin
More results

The mean age was 23.7 ± 4.7 years, and 63.7% of participants were female.

The mean preoperative spherical equivalent (spherical equivalent) was -7.21 ± 2.03 D, and the mean preoperative refractive cylinder was -2.51 ± 0.56 D.

Mean postoperative spherical equivalent was -0.10 ± 0.38 D at 1 month and 0.02 ± 0.31 D at 3 months.

More results

At 3 months, 99% and 84% of eyes achieved uncorrected distance visual acuity of 0.8 decimal or better and 0.9 decimal or better, respectively.

“
Conclusion

Small-incision lenticule extraction Pro performed with the VISUMAX 800 provided favorable early 3-month refractive and astigmatic vector outcomes with a satisfactory safety profile in eyes with high astigmatism.
