PURPOSE: To evaluate clinical outcomes after uncomplicated microincision biaxial cataract surgery and implantation of Incise intraocular lens (IOL). METHODS: This study included 47 eyes of 29 patients (mean age 62.2 ± 8.6 years), who underwent 1.4-mm biaxial cataract surgery with implantation of the Incise IOL (Bausch and Lomb). At third month, surgically induced astigmatism (SIA) was calculated. Three, 6 and 12 months postoperatively, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), corrected near visual acuity (CNVA) LogMAR ETDRS, spherical equivalent refraction (SER), photopic distance corrected contrast sensitivity (CS) with and without glare (85 cd/m(2)) (CSV-1000) were assessed...

Roberto Fernández-Buenaga, Jorge L Alió
Intraocular lens (IOL) explantation after uneventful cataract surgery is rare but associated with a high risk of complications. In the past few years, the number of published reports about IOL explantation has grown significantly and most of them focus on explantation surgery due to spontaneous late IOL in-the-bag dislocations. This is related to the growth of the pseudophakic population, first as a result of longer lifespans, and second, because the improvements in safety and accuracy of phacoemulsification surgery have led to an increased number of phacorefractive procedures performed in younger patients...

Intraocular power calculation is challenging for patients who have previously undergone corneal refractive surgery. The sources of prediction errors for these eyes are well known; however, the numerous formulas and methods available for calculating intraocular lens power in these cases are eloquent testimony to the absence of a definitive solution. This review discusses some of the available methods for improving the accuracy for predicting the refractive outcome for these patients. It focuses mainly on the methods available on the American Society of Cataract and Refractive Surgery (ASCRS) online calculator and provides some practical guidelines for cataract surgeons who encounter these challenging cases...

We report a case of herpetic endophthalmitis following cataract surgery. A 65-year-old man underwent uneventful phacoemulsification and vision improved within the first few postoperative days. However, visual loss with an anterior chamber reaction of ++++ and a ++ vitreous cell were noted in the 4th postoperative week. Repeated intravitreal injection of vancomycin and ceftriaxone, pars plana vitrectomy and removal of the intraocular lens (IOL), and the capsular bag were performed sequentially but in vain. Bacterial, mycobacterial, and fungal culture of the IOL and capsular bag demonstrated negative findings...

Dexamethasone intravitreal implantation has been used in various retinal and uveal pathologies. Common complications include cataract formation and raised intraocular pressure. Although uncommon, migration of the implant has also been well reported. We describe a case with migration of the implant into the anterior chamber in a patient with a scleral-fixated intraocular lens, which was managed noninvasively by pupillary dilatation and positioning of the patient.

A 12-year-old boy was brought with the chief complaint of diminution of vision in his left eye for the past 1 month. History revealed a blunt trauma to his left eye with a wooden stick 6 weeks ago.Visual acuity was 20/20 and hand movement close to face in right and left eye, respectively, without any relative afferent pupillarydefect. Slit-lamp examination showed a total cataractous lens with signs suggestive of suspected posterior capsular (PC) defect. The PC defect was screened initially using B-scan ultrasound of the posterior segment, followed by confirmation of the same using ultrasound biomicroscopy...

RATIONALE: Megalophthalmos anterior is a rare, bilateral, nonprogressive, hereditary, congenital disorder, characterized by the enlargement of all anterior segment structures of the eye, with megalocornea, iris atrophy, and zonular abnormalities commonly found. Usually almost asymptomatic in young patients, with most complaints concerning blurred vision due to the common corneal astigmatism, it might in time lead to several complications including premature cataract formation and pigmentary glaucoma...
