Some features of arcuate corneal incisions (quantity, depth, length and morphology), spectacle independence at a distance and complications were recorded. The uncorrected and corrected distance visual acuity, refraction spherical equivalent, corneal astigmatism were measured (using an OPD-Scan III topographer) before, 1 week and 3 months after surgery. In this clinical interventional study, forty-five cases with cataract and corneal astigmatism (> 0.50D) were treated with corneal arcuate incisions and femtosecond-laser assisted cataract surgery in Vietnam National Institute of Ophthalmology, from January 2017 to May 2018. To assess the efficacy and safety of arcuate corneal incisions in treatment corneal astigmatism during femtosecond laser-assisted cataract surgery. In Vietnam, it has not yet any study about this issue, so we perform this study. Nowadays, along with progress in cataract surgery, the femtosecond laser can produce the arcuate incisions high precisely that help the astigmatic correction. Limbal relaxing incision with bimanual MICS is an easy-to-follow combined surgery to correct preexisting astigmatism with predictable accuracy.Īstigmatic management is an important step to achieve the best visual quality after refractive cataract surgery. Cravy analysis showed that the vector change in cylinder was 1.44 D in the LRI group and 0.18 D in the non-LRI group (P =. Postoperative cylindrical error was significantly lower in the LRI group than in the non-LRI group (0.56 D and 1.51 D, respectively, P =.

009), although no difference was seen in CDVA in either group. Uncorrected distance visual acuity was significantly higher in the LRI group (mean: 0.94) than in the non-LRI group (mean: 0.71, P =. In all cases of astigmatism in the LRI group, incisions for phacoemulsification and IOL insertion did not overlap or affect the LRIs. Postoperative uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), postoperative refractive error, corneal topography, and vector analysis of keratometric change between pre- and postoperative eyes were compared. In a prospective, single-center study, eyes with > or = 0.75 diopters (D) of keratometric astigmatism were randomly assigned to two surgical techniques: 1) bimanual MICS (non-LRI group) or 2) LRI combined with bimanual MICS (LRI group). To evaluate clinical outcomes of limbal relaxing incision (LRI) combined with bimanual phacoemulsification and insertion of an intraocular lens (IOL) developed for bimanual microincision cataract surgery (MICS).
