purpose: to evaluate the efficacy, safety, predictability and stability of implantable collamer lens (icl) and toric icl for the treat­ment of high myopia and high myopic astigmatism, one year prospective study. methods: in this prospective nonrandomized clinical trial, 95 eyes of 51 patients that had icl (31 eyes) and toric icl (64 eyes) were participate in eye research center, department of o...

PURPOSE To evaluate the astigmatic outcomes of wavefront-guided sub-Bowman keratomileusis (WFG-SBK) for low to moderate myopic astigmatism. METHODS This study enrolled 100 right eyes from 100 patients who underwent WFG-SBK for the correction of myopia and astigmatism. The polar value method was performed with anterior and posterior corneal astigmatism measured with Scheimpflug camera combined...

In the two groups of patients with myopic astigmatism the uncorrected near vision was tested after catatract surgery. Each group with 20 patients ages 60-80. All patients enrolled in study have uncorrected far vision 0.5 or better on Snellen tables. In the first group patients were with the rule after surgery myopic astigmatism (1-1.50 Diopter), and in the second group were patients with agains...

purpose : to determine and evaluate the visual acuity (va) and refracion of correcting compound severe myopic astigmatism with the artisan toric intraocular lenses (iols) methods : in this noncontrolled clinical trial, 15 patients with severe astigmatism and at least 2.0 diopters (d) of astigmatism were enrolled. all patients met the inclusion criteria. artisan toric iol implantation was recomm...

Purpose. To assess the amount and the axis orientation of anterior and posterior corneal astigmatism after refractive lenticule extraction (ReLEx) for myopic astigmatism. Methods. We retrospectively examined 53 eyes of 53 consecutive patients (mean age ± standard deviation, 33.2 ± 6.5 years) undergoing ReLEx to correct myopic astigmatism (manifest cylinder = 0.5 diopters (D)). Power vector anal...

OBJECTIVE To evaluate the safety and efficacy of bitoric laser in situ keratomileusis (LASIK) for the correction of simple myopic and mixed astigmatism. DESIGN Retrospective, single-center, and noncomparative case series. PARTICIPANTS Eighty-six eyes of 56 patients were analyzed for this study. Six-month and 1-year follow-up data were available on 86 eyes and 72 eyes, respectively. Eyes wer...

Small Incision Lenticule Extraction (SMILE) is a flap-free intrastromal technique for the correction of myopia and myopic astigmatism. To date, this technique lacks automated centration and cyclotorsion control, so several concerns have been raised regarding its capability to correct moderate or high levels of astigmatism. The objective of this paper is to review the reported SMILE outcomes for...

Forty five eyes with up to 2 dioptres of myopic astigmatism and up to 1 dioptre sphere either plus or minus following cataract extraction and implantation of a monofocal intraocular lens were examined to assess their unaided visual acuities. Forty three percent were able to see 6/12 and N8, and 60% were able to see 6/12 and N10. Subjects with between 1 and 2 dioptres of myopic astigmatism and v...
