purpose: to compare aspheric and spherical hydrophilic intraocular lenses (iols) in terms of contrast sensitivity and visual acuity in photopic and mesopic conditions. methods: this triple-blind randomized clinical trial was performed on 40 eyes of 40 patients at al-zahra eye center, zahedan, iran. the eyes were randomized to standard phacoemulsification procedure with spherical (adapt, b&l;) o...

purpose: to demonstrate an approach to the problems of cataract surgery in extensive iridoschisis methods: four eyes of 2 patients with extensive iridoschisis had cataract surgery by the same surgeon using the techniques that resembled techniques for phacoemulsification in intraoperative floppy iris syndrome (ifis). we used low flow parameters on phacoemulsification, used super-cohesive ophthal...

purpose: to evaluate the effect of phacoemulsification and posterior chamber intraocular lens (pciol) implantation on intraocular pressure (iop) in eyes with chronic angle-closure glaucoma. methods: twenty-two patients with chronic angle-closure glaucoma (cacg) and visually significant cataract were included in our study. all were underwent phacoemulsification and pciol implantation. iop, depth...

OBJECTIVES To investigate differences in surgical time, the distance the surgical instrument travelled and number of movements required to complete manual phacoemulsification cataract surgery versus femtosecond laser cataract surgery. DESIGN Non-randomised comparative case series. SETTING Single surgery site, Moorfields Eye Hospital, UK. PARTICIPANTS 40 cataract surgeries of 40 patients. ...

BACKGROUND Phacoemulsification and intraocular lens (IOL) implantation has resulted in early visual rehabilitation, increased wound stability and improved refractive results. Viscoelastic substances (VES) are important adjuncts in this type of surgery. Use of VES in phacoemulsification can be associated with adverse effects, the most common and potentially dangerous of which is the transient ri...

PURPOSE To compare the performance of sonic phacoemulsification with that of ultrasonic phacoemulsification in regard to 1-day postoperative visual acuity, corneal edema, and procedure efficiency. SETTING Oregon Eye Institute, Eugene, Oregon, USA. METHODS This prospective nonrandomized study comprised 86 eyes with mild to moderate nuclear sclerotic cataract. Forty-three eyes had sonic and 4...

Purpose. To study whether nurse led same-day review (SDR) after uneventful phacoemulsification can replace next-day review (NDR) in terms of safety and efficacy. Setting. Patients are recruited from an ophthalmology outpatient clinic in Hong Kong. Design. A prospective, randomized crossover study conducted from November 2012 to 2014. Methods. Inclusion criteria include cataract surgery naïve pa...

The aim of this study was to compare the correlation of features of cataracts graded by the Lens Opacities Classification System, version III (LOCS III) with recorded operative characteristics during the phacoemulsification. The retrospective study included 245 cases operated on by a single surgeon from October 2003 to March 2004. The cataract was graded at the biomicroscope using the 4 grading...
