Background: Dropped lens fragments into the vitreous are uncommon, but potentially sight threatening complications of cataract surgery. The recommended approach for removal of dropped lens matter is pars plana vitrectomy with or without ultrasonic emulsification with the fragmatome. This study aimed to determine the visual outcome following pars plana vitrectomy for dropped lens fragments complicating cataract surgery at 6 weeks, 3 months and 6 months. Methods: This study is a retrospective review of patients who had PPV as treatment for dropped lens fragments complicating cataract surgery at Ispahani Islamia Eye hospital and Institute...

BACKGROUND: Intraoperative IOLs clouding of several kinds of hydrophilic acrylic intraocular lenses (IOLs) have been reported due to temperature changes. This phenomenon reported previously occurred in cold countries and during the winter months. However, no clinical case was reported about trifocal IOL opacification during operation. We report a case in which acute opacification of the optical region occurred simultaneously when AT LISA tri 839mp(Carl Zeiss) was implanted into the eye...

PURPOSE: The purpose of the study was to investigate the electron microscopic findings of the lens epithelial cells (LECs) in patients with Fuchs uveitis syndrome (FUS) who suffered from cataracts and to compare those with age-matched controls. METHODS: This study was a prospective, comparative case series. The anterior lens capsules (ALC: basement membrane and associated LECs) were taken from 12 eyes of 12 cases of FUS and ten eyes of ten control patients. The ALCs were obtained from cataract surgery and prepared for transmission electron microscopy (TEM)...

PURPOSE: The purpose of the study was to report our initial experience with the transconjunctival Intrascleral Intraocular Lens (SFIOL) fixation with modified Yamane's double-needle technique and flanged haptics. METHODS: This was a prospective interventional study that enrolled 31 consecutive patients undergoing SFIOL with the modified Yamane's technique. All patients underwent comprehensive evaluation including uncorrected and best-corrected vision, intraocular pressure, ultrasound biomicroscopy, endothelial cell density, and macular thickness using optical coherence tomography (OCT)...

PURPOSE: To study the effect of capsular bag irrigation of trypan blue dye (0.06%) on posterior capsular opacification (PCO) in eyes undergoing phacoemulsification. METHODS: This was a randomized, trial conducted at a tertiary eye care center in central India. The study included 50 patients (100 eyes) with senile cataracts who were scheduled for phacoemulsification and intraocular lens (IOL) implantation and were willing to undergo bilateral cataract surgery. One eye of each patient was randomized to one of two groups...

PURPOSE: To compare Endothelial cell(EC) loss following Phacoemulsification (PKE) in pupils of different sizes. METHODS: A prospective double masked observational study in which a total of 150 eyes of 150 patients between 50 & 70 years of age with senile cataract of nuclear sclerosis grade II were enrolled. Patients were allocated into three groups of 50 eyes each in Group A (pupil size <5 mm), Group B (pupil size 5-7 mm) and Group C (pupil size >7 mm). Pupillary size was measured by determining the height of slit on slit-lamp biomicroscope examination...

In existing designs of intraocular lenses (IOLs), optical outcomes are compromised even after perfectly executed surgery. The reason for this is misalignment of optical axis of the eye and its visual axis. There is a need to design an IOL which compensates for this misalignment and hence enhances the optical outcomes of cataract surgery. The present innovation attempts to fulfill this unmet need and optimizes optical outcomes of all IOLs of different optical profiles - spherical, aspheric, toric, and multifocal...

The B-HEX® Pupil Expander (Med Invent Devices) is a disposable 6.5 mm flexible hexagonal device with notches at corners and flanges at sides. Alternate flanges with positioning holes are tucked under the iris to engage the notches to the margin of the pupil to provide a 5.5 mm expanded pupil. Unlike devices with scrolls or pockets which require an injector to avoid snagging the incision, the preloaded B-HEX is inserted and removed through a 1 mm or larger incision using a manipulator or 23-gauge micro-forceps...

The visual outcome of uveitic cataract surgery depends on the underlying uveitic diagnosis, the presence of vision-limiting pathology and perioperative optimization of disease control. A comprehensive preoperative ophthalmic assessment for the presence of concomitant ocular pathology, with particular emphasis on macula and optic nerve involvement, is essential to determine which patients will benefit from improved vision after cataract surgery. Meticulous examination in conjunction with adjunct investigations can help in preoperative surgical planning and in determining the need for combined or staged procedures...

Toric intraocular lenses (IOLs) are the procedure of choice to correct corneal astigmatism of 1 D or more in cases undergoing cataract surgery. Comprehensive literature search was performed in MEDLINE using "toric intraocular lenses," "astigmatism," and "cataract surgery" as keywords. The outcomes after toric IOL implantation are influenced by numerous factors, right from the preoperative case selection and investigations to accurate intraoperative alignment and postoperative care. Enhanced accuracy of keratometry estimation may be achieved by taking multiple measurements and employing at least two separate devices based on different principles...

REVIEW
Aazim A Siddiqui, Uday Devgan
Cataract surgery is the most performed surgical procedure in the field of ophthalmology. The process of intraocular lens (IOL) calculations is a critical step to achieving successful outcomes. Many IOL formulae exist to guide surgeons through the difficult process of picking the most appropriate lens to achieve a certain target refraction. However, these formulae reach within 0.50 diopters of the target refraction only 75% of the time, leaving 25% of the eyes with a significant refractive surprise. A literature review was performed to investigate all the relevant published material on the history, progress, and recent advancements of IOL calculations...

PURPOSE: To analyze clinical outcomes and intraocular pressure (IOP) control following scleral-glued intraocular lens (IOL) fixation in eyes with pseudoexfoliation (PXF). METHODS: A retrospective chart review and outcome analysis was performed on a series of eyes undergoing glue-assisted, scleral-fixated ('scleral-glued') IOL insertion in the setting of PXF and poor or absent capsular support. RESULTS: 28 eyes were included in the study. The indications for scleral-glued IOL fixation included late endocapsular IOL dislocation (21/28, 75%), exchange for iris-fixated IOL due to complication (4/28, 14%), subluxed crystalline lens (2/28, 7%), and aphakia after complicated cataract surgery (1/28, 4%)...

Uveitis is a leading causes of blindness worldwide, and the development of cataracts is common due to both the presence of intraocular inflammation and the most commonly employed treatment with corticosteroids. The management of these cataracts can be very challenging and often requires additional procedures that can compromise surgical results. The underlying disease affects a relatively young population at higher risk of complications. Preoperative control of inflammation/quiescent disease for at least three months is generally accepted as the minimum amount of time prior to surgical intervention...
