Sutureless ciliary sulcus supported intraocular lens with transiridal anchoring haptics.
2003
We report a technique for implanting intraocular lenses (IOLs) in the ciliary sulcus in eyes without capsule support. The IOL design allows it to be implanted without fixation sutures. The lens was implanted in 3 aphakic eyes without capsule support.
Effect of head position on refraction in aphakic and phakic silicone-filled eyes.
1997
BACKGROUND The refraction of the eye is altered significantly after the instillation of silicone oil into the vitreous cavity because of the silicone oil's high refractive index. The degree of the refractive change shows diurnal variation and depends on the patient's head position. PATIENTS AND METHODS To analyze the degree and time course of refractive changes with respect to head position, the authors performed objective refraction in five aphakic and five phakic silicone oil-instilled eyes with attached maculae using an automatic hand-held refractometer. In each patient, 25 measurements were taken at short intervals using a hand-held autorefractometer with the patient in different positi…
Axial Elongation following Cataract Surgery during the First Year of Life in the Infant Aphakia Treatment Study
2012
PURPOSE To compare ocular axial elongation in infants after unilateral cataract surgery corrected with a contact lens (CL) or primary intraocular lens (IOL) implantation. METHODS Baseline axial length (AL) was measured at the time of cataract surgery (1-6 months) and at age 1 year. AL at baseline and age 1 year and the change in length/mo were analyzed in relation to treatment modality, cataractous versus fellow eye, and age at surgery using linear mixed models. RESULTS Mean baseline AL did not differ between the CL and IOL groups for either cataractous or fellow eyes. Eyes with cataracts were shorter than fellow eyes by an average of 0.6 mm (95% confidence interval [CI], 0.4-0.8 mm; P < 0.…
New Forceps and Spatula for Easy Retropupillary Implantation of Iris Claw Lenses in Aphakia: Experience in 4 Years of Use
2008
PURPOSE. Retropupillary implantation of an iris claw lens offers a rapid and atraumatic approach for rehabilitation of aphakic eyes. The difficulty in the implantation process arises because of the possibility of losing the intraocular lens (IOL) into the vitreous cavity and the need to change the hand holding the forceps during the enclavation. M ETHODS. The new forceps design radically changes the method of grasping an IOL. It contains an extendable supporting plate with a hook-like end. The instrument achieves a horizontal three-point fixation at the edge of the implant in the 6 and 12 o’clock position in order to prevent slippage into the vitreous cavity during the inclination. The supp…
