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...

Three main designs of posterior chamber lenses in 140 cases have been reviewed. The visual results are satisfactory; patient satisfaction is good; and postoperative complications are limited to anterior dislocation of the feet of the lens and the necessity to wash out cortical remnants from behind the prosthesis in a small percentage of cases. The posterior chamber prosthesis is free from some ...

PURPOSE To determine the efficacy of the astigmatism correction following toric intraocular lens (IOL) and toric phakic IOL (pIOL) implantation in eyes with no previous ocular surgery and in postkeratoplasty (PKP) eyes. In addition, changes in corneal astigmatism were determined. METHODS Astigmatism was analyzed in 35 eyes with an AcrySof toric IOL, 35 eyes with an Artiflex toric pIOL, 50 eye...

In a prospective controlled trial 290 consecutive patients were randomly allocated a polymacon or a poly(methyl methacrylate) (PMMA) intraocular lens. Early Treatment of Diabetic Retinopathy Study (ETDRS) acuity charts gave similar results with both lenses. However Pelli-Robson contrast sensitivity charts gave a better result with PMMA lenses. Polymacon lenses appeared to remain free of any adh...

The case for capsular bag fixation of the Sinsky-Kratz type of posterior chamber intraocular implant lens is presented, and the various methods in use to position implant lenses are outlined. The new forceps are described and the rationale for their adoption and use is given in an illustrated, step-by-step fashion. Their additional use in anterior chamber intraocular lens implantation is mentio...

This paper presents a study designed to compare optical quality expressed through PSF (Point Spread Function), MTF (Modulation Transfer Function) and OSI (OqasTM Scattering Index) between several intraocular implants for presbytia surgery. These are: TecnisTM ZM900, Acri.LISATM 366D, ReSTOR SN6AD1 and Crystalens® HD. Historically, research on the optical quality of intraocular lenses developed ...

In their recent paper, Ortiz et al. studied the optical performance of monofocal and multifocal intraocular lenses (IOLs) in the human eye. Their main conclusion was that of the IOLs studied, the hybrid refractive–diffractive IOLwas the least affected by pupil diameter in terms of intraocular aberrations. This IOL type also showed a smaller increase in optical aberrations during pupil dilation....

Implantation of intraocular lens with Iris-fixation is a safe, efficient and predictable surgical procedure, which empowers the refractive surgeon with singular capabilities. Among their advantages are the reversibility, preservation of accommodation and a broad spectrum of ametropic correction. This lens also appears to be a valid option, with a favorable complication rate, for the treatment o...

The use of multifocal intraocular lenses (IOLs) is a great advance in the treatment of patients with cataract allowing near and distance uncorrected visual acuity recovery. However patients with some degrees of corneal astigmatism have some limitations. We present 3 cases that were indicated for phacoemulsitfication and multifocal intraocular lens implant (AcrySof Restor, Alcon Labs) after limb...

A woman presented with a painful eye 6 weeks after cataract extraction and intraocular lens implantation. In the past she had had a sector iridectomy for iris bombé caused by chronic anterior uveitis. On examination the three central corneal sutures were absent, whilst the medial and lateral sutures had broken and were protruding from the section. The eye was quiet and the section intact. Combi...
