story dislocated Posterior chamber intraocular Lens Management
P osterior chamber intraocular lenses (IOLs) are exquisitely engineered to provide excellent vision when implanted into a stable capsule following extracapsular cataract extraction. If the lens capsule or the supporting lens zonules fail, and the IOL dislocates, vision usually deteriorates. Unfortunately, just as cars are not designed to be easily fixed after crashing, IOLs are not designed to ...
متن کاملPupillary block following posterior chamber intraocular lens implantation in adults.
BACKGROUND Pupillary block rarely occurs after cataract extraction with posterior chamber intraocular lens implantation. METHODS A series of six patients (seven eyes) treated for pupillary block after posterior chamber intraocular lens implantation between 1990 and 2001 is described; in one eye, the attack occurred after phacoemulsification. RESULTS The interval between pupillary block deve...
متن کاملContrast sensitivity in patients with posterior chamber intraocular lens implants.
Divergent contrast sensitivity findings have been reported in patients with intraocular lens implants. In this study, contrast sensitivity to stationary sine-wave gratings of six spatial frequencies from 0.5 to 22.8 cycles/degree was measured psychophysically in 13 patients with posterior chamber intraocular lens implants and in 10 controls. Corrected visual acuity was 0.7 to 1.0 in the intraoc...
متن کاملpresumed transcorneal extrusion of a posterior chamber intraocular lens
purpose: to describe a case with a rare complication of posterior chamber intraocular lens (pc-iol) implantation in a patient who had undergone extracapsular cataract extraction (ecce) two years before case report: a 80-year-old diabetic woman presented with an exposed pc-iol in her left eye with a history of mechanical trauma. slit-lamp examination revealed an extruded pc-iol lied on the anter...
متن کاملUveitis-glaucoma-hyphema syndrome after posterior chamber intraocular lens implantation.
This article describes uveitis-glaucoma-hyphema (UGH) syndrome following posterior chamber intraocular lens (PCIOL) implantation in a 51-year-old male patient who had had intermittent blurred vision for 2 years prior to cataract surgery. We found the lens haptics fixed in the sulcus and the lens rotated. The lens was extracted and a new implant inserted with a transscleral suture. Etiology of t...
