Dear Editor, Berger’s space is a potential compartment that can present behind the crystalline lens but is not open in normal situations. This space is formed by the posterior lens surface and anterior vitreous face and is circumscribed by Weiger’s ligament [1]. Except for some congenital abnormalities, Berger’s space is rarely involved in ocular disease because of vulnerability of structures s...

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...

PURPOSE This study aimed to assess the value of intraoperative aberrometry (IA) in determining the intraocular lens (IOL) sphere power in eyes with no previous ocular surgery. PATIENTS AND METHODS We conducted a retrospective review of patients who underwent uncomplicated cataract surgery where standard preoperative (Preop) measurements and IA were performed. Calculated IOL sphere powers and ...

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...

PURPOSE To compare accuracy of intraocular lens (IOL) power calculation formulae in infantile eyes with primary IOL implantation. DESIGN Comparative case series. METHODS The Hoffer Q, Holladay 1, Holladay 2, Sanders-Retzlaff-Kraff (SRK) II, and Sanders-Retzlaff-Kraff theoretic (SRK/T) formulae were used to calculate predicted postoperative refraction for eyes that received primary IOL impla...

PURPOSE To establish a novel murine intraocular lens (IOL) implantation model to study the protective effects of colored-IOLs against retinal phototoxicity. METHODS Two-millimeter diameter IOL buttons were created from IOLs for clinical use. Extra-capsular crystalline lens extraction and IOL implantation were performed in BALB/c mice using a technique similar to human cataract surgery. For li...

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...
