ARTICLE

Comparison of clinical outcomes between vector planning and manifest refraction planning in small-incision lenticule extraction for myopic astigmatism

Purpose
To compare clinical outcomes of small-incision lenticule extraction (SMILE) between manifest refraction and vector planning for myopic astigmatism with high ocular residual astigmatism (ORA).
Setting
Yonsei University College of Medicine and Eyereum Eye Clinic, Seoul, Korea.
Design
Prospective, randomized, comparative case series.
Methods
We included 114 eyes of 114 patients with myopic astigmatism and ORA ≥0.75 diopters (D); patients underwent SMILE and were randomized into the manifest refraction-planning (59 eyes) or vector planning group (55 eyes). Visual acuity, manifest refraction, corneal topography, and corneal aberration were measured preoperative and postoperative. Outcomes at 6 months postoperatively were compared between the groups.
Results
The mean uncorrected and corrected distance visual acuity, safety and efficacy indices, and aberrometric values were comparable between the 2 groups at 6 months after SMILE. Postoperative refractive cylinder differed significantly between the groups (-0.22 ± 0.18 D and -0.14 ± 0.16 D in the manifest refraction and vector planning groups, respectively; P = .02). Postoperative corneal toricity (1.07 ± 0.40 D vs 0.84 ± 0.39 D; P = .003) and ORA (0.98 ± 0.31 D vs 0.85 ± 0.32 D; P = .037) differed significantly between the groups, with favorable results for the vector planning method.
Conclusions
In myopic astigmatism with high ORA, manifest refraction and vector planning in SMILE were effective with comparable visual outcomes; vector planning showed significantly better postoperative refractive and corneal astigmatism and ORA. Use of vector planning may improve refractive outcomes in SMILE cases with high ORA.

In laser corneal refractive surgeries for astigmatism correction, 2 treatment strategies are used, based on the manifest refraction or the shape of the cornea. Although the cylinder of the manifest refraction is mainly caused by anterior corneal astigmatism, corneal topographic astigmatism is not always consistent with the refractive cylinder. The difference between corneal astigmatism and refractive cylinder at the corneal plane can be described as the ocular residual astigmatism (ORA), calculated as the vectorial difference. This difference is caused by the posterior corneal surface and crystalline lens, as well as by nonoptical perceptive factors. Previous studies have shown that ORA in the healthy astigmatic eyes that underwent corneal refractive surgery was fairly large, with a mean of 0.73 to 0.81 diopters (D), and even 34% to 60% over 1.0 D.

High ORA has been shown to negatively affect the postoperative visual and refractive outcomes after...
