SUMMARY Iris-claw intraocular lens (ICIOL) for aphakia needs a large 5.4 mm corneal incision for its implantation. The technique needs corneal suture, associated with some postoperative astigmatism. Foldable ICIOL is used in phakic patients undergoing refractive surgery and has the advantage of a sutureless small corneal incision. We report a case of a high myopic patient with dislocated intrao...

PURPOSE To evaluate effects and safety of primary phacoemulsification plus intraocular lens implantation for controlled chronic angle-closure glaucoma (CACG) or primary angle-closure (PAC). DESIGN Prospective, non-randomized comparative trial. METHODS Two treatment groups were used. The IOL group included the use of phacoemulsification plus intraocular lens (IOL) implantation in 27 eyes. Th...

PURPOSE To establish a fully human in vitro culture model with which to test the putative effects of intraocular lens (IOL) designs in preventing posterior capsule opacification (PCO) after cataract surgery. METHODS A sham cataract operation was performed to prepare human capsular bags from donor lenses. In one capsular bag of a donor pair, an intraocular lens (PMMA round-edge IOL or acrylic ...

Formulas For Intraocular lens Power calculatIon Modern cataract surgery replaces the natural lens of the eye with an intraocular lens (IOL). After surgery, the optical system of the eye will consist of two major refractive elements, the cornea and the newly inserted IOL. This two-lens system is at the basis of IOL power calculation. To facilitate calculations, both the cornea and the IOL are co...

We discuss a case of bipseudophakia with secondary dislocation of a posterior chamber intraocular lens (IOL) into the anterior chamber that was managed by explantation of the anterior and posterior chamber IOLs and implantation of an iris claw IOL.

RATIONALE Although transscleral-fixated intraocular lens (IOL) implantation has been the most frequently chosen treatment for patients with inadequate capsule support, the ghost pupillary capture phenomenon did not cause enough attention. PATIENT CONCERNS We present an unusual case withintermittent pupillary capture of intraocular lens. DIAGNOSIS After 5 minutes staying in the dark environm...

PURPOSE To report an intraocular lens opacification case during cataract surgery. METHODS An 80-year-old woman with a history of hypertension and type 2 diabetes mellitus presented with advanced nuclear cataract in her left eye and underwent coaxial phacoemulsification through a 1.8-mm micro-incision and insertion of an in-the-bag intraocular lens (IOL). There was subsequently rapid, homogeno...

The capsule of the crystalline lens, if sufficiently present, is used as a support tissue for intraocular lens (IOL) implantation surgery performed on vitrectomized eyes. Eye trauma or iatrogenic damage during complicated cataract surgery, loss of position and zonule connections of the crystalline lens, and IOL via dislocation may cause loss of support tissue for lens capsule implantation prior...

The most effective treatment for cataracts is to remove the cloudy crystalline natural lens and implant an intraocular (IOL) in its place. These refractive provide same focusing as do lens. Two IOLs are designed analyzed this paper—these IOL made of (PMMA, Acrylic). quality retinal image compared with healthy eye, which based on (Liou-Brennan) eye model) LBEM). Polychromatic Point Spread Functi...

PURPOSE To report the results of pars plana vitrectomy (PPV) for retained lens fragments with implantation of an Artisan intraocular lens (IOL) (Ophtec) to correct aphakia. SETTING University-based referral center. METHODS In this retrospective case-controlled study, patients who had had a PPV to remove dislocated lens fragments and implantation of an Artisan IOL for pseudophakic correction...
