Open-capsule intraocular lens to prevent posterior capsule opacification.

Purpose: To develop a single-piece open-capsule intraocular lens (IOL) that can be inserted through a small incision and that prevents posterior capsule opacification (PCO) by expanding the capsule and circulating aqueous humor into the capsular bag.

Setting: Department of Ophthalmology, Dokkyo Medical University, Tochigi, Japan.

Design: Experimental study.

Clinical evaluation of the transparency of hydrophobic acrylic intraocular lens optics.

Purpose: To clinically evaluate postoperative changes in the transparency of hydrophobic acrylic intraocular lenses (IOLs).

Setting: Department of Ophthalmology, Dokkyo Medical University, Tochigi, Japan.

Design: Case-control study.

Efficacy of ophthalmic nonsteroidal antiinflammatory drugs in suppressing anterior capsule contraction and secondary posterior capsule opacification.

Purpose: To evaluate the efficacy of ophthalmic nonsteroidal and steroidal antiinflammatory drugs in preventing anterior capsule contraction and secondary posterior capsule opacification (PCO) using an experimental cataract model.

Setting: Department of Ophthalmology, Dokkyo Medical University, Tochigi, Japan.

Methods: Eight-week-old albino rabbits weighing about 2 kg each had phacoemulsification and intraocular lens implantation.

Comparison of anterior capsule contraction between 5 foldable intraocular lens models.

Purpose: To compare anterior capsule contraction in cataract patients having implantation of 1 of 5 foldable intraocular lens (IOL) models and evaluate lens epithelial cell (LEC) adhesion to each model.

Setting: Department of Ophthalmology, Dokkyo Medical University, Tochigi, Japan.

Methods: This study comprised 115 patients (126 eyes) without systemic or ocular complications who had phacoemulsification with IOL implantation.

[Protective effect on the corneal endothelium and remaining effect at the anterior chamber for three different kinds of viscoelastic devices].

Purpose: The present study was performed to evaluate the corneal endothelium protection and anterior chamber stagnation abilities of three different types of viscoelastic substances (Healon, Viscoat, HealonV).

Methods: Viscoelastic substances were selected at random for 120 eyes with cataracts, and the postoperative reduction rates of the corneal endothelium cells were compared. The residual viscoelastic substances after filling of the anterior chamber of pig eyes and aspiration with a handpiece were measured by an anterior eye segment image analysis system.
