PURPOSE To analyze the factors related to changes in astigmatism before and after suture removal in patients who underwent penetrating keratoplasty (PK). METHODS The study group consisted of 171 consecutive PKs in 171 patients. Keratometric astigmatism was measured before and after suture removal in all patients. The vectorial difference for each eye was calculated between the examination bef...

PURPOSE The purpose of this study was to evaluate the refractive and visual outcomes of wavefront-guided laser in situ keratomileusis (LASIK) in eyes with myopic astigmatism and cylindrical component ≥2.0 diopter (D). METHODS In this retrospective study, 611 eyes that underwent LASIK for simple or compound myopic astigmatism were analyzed. Preoperative refractive cylinder ranged from -2.00 D ...

BACKGROUND To evaluate the refractive outcomes for the correction of low to moderate astigmatism up to 1 year following small incision lenticule extraction (SMILE) surgery. METHODS This retrospective study enrolled 98 eyes from 98 patients who underwent SMILE surgery for the correction of myopia and astigmatism. Only right eyes were included in this study to avoid the bias of orientation erro...

the objective of the present study was to compare single segment and double segment intacs rings in the treatment of post-lasik ectasia. in this interventional study, 26 eyes with post-lasik ectasia were assessed. ectasia was defined as progressive myopia regardless of astigmatism, along with topographic evidence of inferior steepening of the cornea after lasik. we excluded those with a history...

This study was carried out with the objective of finding refractive status of patients undergoing phacoemulsification surgery for cataract extraction. Success of cataract surgery can be quantified with the improvement in visual acuity with least amount of refractive error. Prospective study of 44 patients was done pre operatively and with subsequent follow up in the first, third and eighth week...

To compare surgically induced astigmatism after manual small incision cataract surgery and phacoemulsification surgery. 2) know the prevalence of pre-existing astigmatism, it’s magnitude type patients with cataract. 3) calculate average also to change in it first month 4) its 5) study changes effect on vision 6) by straight frown operation. The was carried out Department Ophthalmology, P.D.U go...

Preoperative corneal astigmatism higher than 1 D is present in up to 30–47% of eyes with cataracts. Proper correction astigmatism, apart from the adequately determined spherical power artificial intraocular lens (IOL), main factor ensuring desired result procedure manifested as postoperative spectacle’s independence, visual function, and a – patient satisfaction. Toric IOL implantation allows s...

We report a case of controlled buccal pemphigus vulgaris with compound moderate myopia with astigmatism that was treated with photorefractive keratectomy with mitomycin-C (PRK+MMC) in both eyes. The preoperative manifest refraction was -6.50 sphere and -5.5 -0.75 x 20 in the right eye and left eye, respectively, with a best corrected visual acuity of 10/10 in both eyes. Seven months after surge...

PURPOSE To report the outcomes of a simple and effective office-based procedure for the correction of astigmatism after deep anterior lamellar keratoplasty (DALK). METHODS This study enrolled 24 consecutive keratoconic eyes that developed an intolerable amount of graft astigmatism after DALK. The location and extension of steep semi-meridians were determined using corneal topography. Office-b...
