Management of low astigmatism in implantable collamer lens surgery: opposite clear corneal incisions versus toric implantable collamer lens.

Both the T-ICL and OCCI techniques provided excellent results in terms of safety and efficacy. T-ICL surgery was shown to be more predictable and accurate for correcting low astigmatism with a lower postoperative spherical equivalent and less residual astigmatism compared to incisional management.
