purpose: to describe the biometric changes and their effect on intraocular lens (iol) power calculation after trabeculectomy and to compare the accuracy of four formulas namely srk/ii, srk/t, holladay and hoffer q for iol power calculation in these patients. methods: thirty-four eyes of 31 glaucoma patients who were scheduled for primary trabeculectomy were enrolled. a non-contact biometry devi...

Opacification of a hydrophilic acrylic intraocular (IOL) lens is a rare phenomenon. We herein report a case of a 57-year man complaining of decreased vision at left eye for the last 4 months. He had undergone phacoemulsification with IOL implantation 2 years back. IOL opacification was observed through slit-lamp. IOL exchange was carried out. The exchanged IOL and a new lens of the same model w...

PURPOSE To evaluate refractive and visual outcomes of secondary piggyback intraocular lens implantation in patients diagnosed as having residual ametropia following segmental multifocal lens implantation. METHODS Data of 80 pseudophakic eyes with ametropia that underwent Sulcoflex aspheric 653L intraocular lens implantation (Rayner Intraocular Lenses Ltd., East Sussex, United Kingdom) to corr...

Phakic intraocular lenses revolutionize refractive surgery and continue to serve as an excellent option for vision correction in patients who are not ideal candidates for laser vision correction. This article will review special indications of phakic intraocular lenses in the clinical practice.

PURPOSE To compare, as a function of pupil size, the through-focus performance and halo features of four diffractive intraocular lenses (IOLs). METHODS Three diffractive bifocal IOLs (ReSTOR +2.5 D SV25T0, Tecnis +2.75 D ZKB00, and AT LISA +3.75 D 809M) and a diffractive trifocal IOL (AT LISA tri +3.33 D, +1.66 D 839MP) were tested in vitro in a modified International Organization for Standar...

We present a case of fulminant panuveitis following iris suture fixation of a posterior chamber intraocular lens. We hypothesize that the zonular dehiscence allowed the inflammatory cells in the anterior compartment to gain access to the posterior segment mimicking endophthalmitis or toxic anterior segment syndrome. Also certain bulky lens designs, like the current Rayner hydrophilic acrylic le...

Phacoemulsification with foldable intraocular lens (IOL) implantation has several advantages because of smaller incision and sutureless technique. The visual recovery is usually fast and any surgically induced astigmatism can be kept at lowest. With increased number of trained phacosurgeons in Nepal, more phacosurgeries with foldable lens implantation are being done. Main purpose of this articl...

PURPOSE To evaluate the clinical efficacy and complications of intraocular lens (IOL) exchange. METHODS A review of medical records was performed for 52 eyes that had undergone an IOL exchange due to IOL opacification. Surgical complications and their incidences were analyzed. The mean best corrected visual acuity (BCVA) after the IOL exchange was compared with the mean pre-exchange BCVA and ...

Purpose To assess the outcome of cataract surgery with hydrophilic acrylic intraocular lens (IOL) implantation in children with congenital and developmental cataracts. Method A retrospective review of medical records of children with congenital or developmental cataracts who underwent cataract surgery with hydrophilic IOL implantation, from January 2011 to December 2014 in a tertiary eye hosp...
