BACKGROUND Improvement in surgical devices and intraocular lenses has made modern cataract surgery a safe procedure with decreasing complication rates. Intraocular lens dislocation is a serious complication after cataract surgery. Although most dislocations occur during the first week postoperative period, late intraocular lens dislocation occurring 3 months or later post-surgery has been repor...

Design, fabrication, testing, and performance of an x-ray lens assembly are described. The assembly consists of a number of precisely stacked and aligned parts, each of which is a section of an extruded aluminum piece having 16 parabolic cavities. The wall thickness between adjacent cavities is 0.2 mm. By stacking a number of long, extruded parts and cutting the assembly diagonally, a variable-...

Penetrating ocular trauma is one of the most important causes of vision loss, especially in men, and can be associated with intraocular foreign bodies. The incidence of intraocular cilia after trauma is very low. Here we report the case of a 24-year-old man who visited Poostchi Ophthalmology Clinic (Shiraz, Iran) due to a gradual vision loss in his left eye over the past 2 months. The probable ...

OBJECTIVE To evaluate the efficiency of long-term cataract surgery using low-cost intraocular lens implantation in community campaigns. METHODS Fifty-eight randomly selected patients were evaluated four years after phacoemulsification and Ioflex intraocular lens implantation. Causes of low visual acuity related to the intraocular lens were evaluated, and treatment costs were calculated. RES...

purpose: to compare the results of three-piece and one- piece hydrophobic acrylic posterior chamber intraocular lens (iol) with poly methyl metacrylate (pmma) iol implanted during lensectomy, posterior capsulotomy and anterior vitrectomy for congenital or developmental cataract. methods: this is a historical cohort study conducted on patients with congenital or developmental cataract who underw...

purpose: to compare the effect of implantation of a single-piece hydrophilic foldable acrylic intraocular lens (iol) with rectangular optic edge and a single-piece polymethyl methacrylate (pmma) iol with rounded optic edges on posterior capsular opacification )pco(. methods: this randomized clinical trial study comprised 74 eyes with senile cataract in an otherwise normal eye in patients older ...

purpose: to evaluate the efficacy and safety of the artisan phakic intraocular lens (piol) for the correction of high myopia. methods: in this prospective study of 22 eyes of 14 patients with high myopia, artisan piols (ophtec bv) were implanted. uncorrected visual acuity (ucva), best corrected visual acuity (bcva), refraction, astigmatism, safety, and predictability were analyzed. results: the...

PURPOSE To report the results of a new technique for intraocular lens scleral fixation of temporary haptic externalization and four-point fixation for enhanced stability. METHODS Two 10-0 polypropylene strands were fixed at two points 2 mm apart on each haptic of a conventional three-piece intraocular lens, using our previously reported method of temporary haptic externalization after injecto...
