purpose : to evaluate the near visual performance of an accommodative intraocular lens (iol) tetraflex, in comparison to a standard monofocal foldable iol in cataract surgery. setting: eye research center , farabi eye hospital , department of ophthalmology, tehran university of medical sciences, iran . methods : forty six eyes of 23 patients with cataract underwent phacoemulsification and accom...

The performance of an intraocular lens is determined by several factors such as the surgical technique, surgical complications, intraocular lens biomaterial and design, and host reaction to the lens. The factor indicating the biocompatibility of an intraocular lens is the behavior of inflammatory and lens epithelial cells. Hence, the biocompatibility of intraocular lens materials is assessed in...

INTRODUCTION Spontaneous dislocation of intraocular lens with bag is rare. METHODS We report a case of a 56-year-old male who presented with spontaneous anterior dislocation of an in-the-bag intraocular lens 3 years after manual small incision cataract surgery. He had undergone manual small incision cataract surgery with foldable acrylic intraocular lens implantation, and 18 months after cata...

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...

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...
