One of the most common cause decrease vision in a pseudophakic patient is formation posterior capsular opacification (PCO) which affected by several factors like design implanted intraocular lens (IOL) and material IOL. PCO incidence has been reported to be 20.7% at 2 years & 28.5% 5 years. Decrease because necessitates capsulotomy with neodymium yttrium aluminum garnet (Nd-YAG) laser create sm...

PURPOSE The aim of this study was to evaluate the operational impact of using preloaded intraocular lens (IOL) delivery systems compared with manually loaded IOL delivery processes during routine cataract surgeries. METHODS Time and motion data, staff and surgery schedules, and cost accounting reports were collected across three sites located in the US, France, and Canada. Time and motion dat...

Previous determination of the nucleotide sequence of the iol region of the Bacillus subtilis genome allowed us to predict the structure of the iol operon for myo-inositol catabolism, consisting of 10 iol genes (iolA to iouJ); iolG corresponds to idh, encoding myo-inositol 2-dehydrogenase (Idh). Primer extension analysis suggested that an inositol-inducible promoter for the iol operon (iol promo...

PURPOSE To determine whether rotational stability is improved with the longer Staar toric intraocular lens (IOL). SETTING A private practice, Los Altos, California, USA. METHODS Staar Surgical manufactures toric plate-haptic IOLs under +24.0 diopters (D) in 2 lengths. Fifty consecutive eyes requiring toric IOL spherical powers less than +24.0 D received the longer toric IOL (TL; 11.2 mm) us...

Summary: An overview on polypseudophakia (‘piggyback’ intraocular lens [IOLs]) is given. Requirements on a sulcus-supported supplementary IOL are defined. Two-year results of a new IOL (Sulcoflex®) are presented and indications for this IOL are defined. Methods: The IOL is especially designed for implantation into the ciliary sulcus in pseudophakic eyes (piggyback). It is a single-piece implant...

OBJECTIVE To present options for managing a patient with a dislocated intraocular lens (IOL) in the presence of a second, nondislocated IOL. METHODS A review of 3 consecutive cases and the surgical maneuvers used in managing them. RESULTS The anterior chamber IOL was removed after scleral fixating the dislocated posterior chamber IOL in 1 case with corneal disease. The foldable, dislocated,...

BACKGROUND Unexplained variation in induction of labour (IOL) rates exist between hospitals, even after accounting for casemix and hospital differences. We aimed to explore factors that influence clinical decision-making for IOL that may be contributing to the variation in IOL rates between hospitals. METHODS We undertook a qualitative study involving semi-structured, audio-recorded interview...

Postoperative refractive outcome largely depends on the accuracy of calculating power of implanted IOL. Lens power calculation can be done by conventional ultrasound biometry and partial coherence laser interferometry (IOL Master). The aim was to compare the accuracy of IOL power calculations using conventional ultrasound biometry and partial coherence laser interferometry.40 eyes were included...
