Straight-entrance, sclerocorneal valve incision with horizontal sutures for poly(methyl methacrylate) intraocular lenses.

Self-sealing sclerocorneal tunnel incisions with an external frown entry are widely used for implantation of poly(methyl methacrylate) intraocular lenses. Although safe and effective, these incisions have certain drawbacks. We developed a wound construction in which a straight external incision is used in conjunction with a tension-free, infinity-type suture.

Topical versus peribulbar anesthesia in clear corneal cataract surgery.

Purpose: To evaluate the efficacy of topical anesthesia as an alternative to peribulbar anesthesia in clear corneal cataract surgery.

Setting: Department of Ophthalmology, University of Vienna, Austria.

Methods: In this prospective, double-blind clinical trial, 36 patients had bilateral cataract surgeries performed from 1 to 3 months apart.

In vivo study of cell reactions on poly(methyl methacrylate) intraocular lenses with different surface properties.

Purpose: To evaluate the biocompatibility of three poly(methyl methacrylate) (PMMA) intraocular lenses (IOLs) with different surface properties.

Setting: University Eye Clinic, Vienna, Austria.

Methods: Cell reactions on the surfaces of unmodified, heparin-surface-modified (HSM), and surface-passivated (SP) PMMA IOLs were documented in vivo using a Zeiss specular microscope.

Long-term results of combined trabeculectomy and small incision cataract surgery.

We did a prospective study of 49 eyes (36 patients) with coexisting cataract and glaucoma who had combined trabeculectomy, phacoemulsification, and implantation of a folded polyHema intraocular lens through the trabeculectomy opening. Preoperatively, intraocular pressure (IOP) was controlled (< 20 mm Hg) in 13 eyes on a mean of 2.2 medications and uncontrolled (> 20 mm Hg) in 36 eyes on a mean of 2.

[Pseudoexfoliation syndrome--a risk factor in modern cataract surgery?].

Background: The pseudoexfoliation (PEX) syndrome has been described in the ophthalmic literature as a major risk factor of cataract surgery. Most of the authors have reported extracapsular cataract extraction (ECCE) complication rates of more than 10% for zonular dialysis, capsular rupture, and vitreous loss. However, Osher et al.

Endocapsular hematoma with biconvex posterior chamber intraocular lenses.

We describe ten cases of endocapsular hematoma that developed in the early postoperative period after cataract or combined glaucoma and cataract surgery. After capsulorhexis and phacoemulsification, one of three types of posterior chamber lenses with biconvex optics was implanted in nine eyes. In one eye, a convex-plano poly(methyl methacrylate) lens was implanted.

No-stitch, small incision cataract surgery with flexible intraocular lens implantation.

Small incision cataract surgery has several advantages over conventional surgery, including faster postoperative visual rehabilitation. We evaluated 100 consecutive cases of no-stitch, small incision surgery with a square sclerocorneal tunnel and a flexible intraocular lens. Permanent self-sealing of the wound seemed to increase intraoperative safety considerably.

Evaluation of 100 consecutive IOGEL 1003 foldable bag-style lenses implanted through a self-sealing tunnel incision.

The IOGEL 1003 hydrogel lens, designed for better capsular bag fit, was implanted in 100 consecutive eyes. We evaluated the visual and morphological results obtained with a mean follow-up of six months. Visual acuity was within Food and Drug Administration standards; however, morphological results were less satisfactory.

Evaluation of the first 100 consecutive PhacoFlex silicone lenses implanted in the bag through a self-sealing tunnel incision using the Prodigy inserter.

We evaluated the performance of the PhacoFlex silicone lens with open polypropylene loops and the disposable Prodigy inserter in a series of 100 consecutive no-stitch cases. Loading the lens into the PRO-1A inserter model was easy, as was inserting it through a 4 x 4 mm self-sealing sclerocorneal tunnel incision. If the chamber was deep and the capsular fornix expanded, unfolding the polypropylene loops was safe and direct bag placement was always possible.

Clinical results with three different kinds of small optic PMMA-IOLs.

In this prospective study the clinical results using three different small optic IOLs are presented. The best results were achieved in those cases with an anterior capsule rim overlapping the entire optic periphery. In those cases with sulcus fixation, haptic in/out and optic in/out positions a higher percentage of capsule fibrosis (Soemmering's rings) was documented (sulcus fixation: 100%, haptic in/out position: 75%, optic in/out position: 65.

[Pneumatic retinopexy--a study of 7 years experience].

Background: The goal of this study is the evaluation of effectivity and the complications of pneumatic retinopexy in the treatment of rhegmatogenous retinal detachment as a long-term follow-up.

Material And Methods: This retrospective long-term study covers 89 eyes with rhegmatogenous retinal detachment treated by pneumatic retinopexy between January 1985 and December 1991. With a postoperative follow-up averaging 4.

Ocular findings in asymptomatic amateur boxers.

A group of 25 active, asymptomatic, amateur boxers were examined to evaluate the nature and incidence of ocular pathologic conditions in amateur boxing. An approximately age-matched group of 25 men who were not boxers was used as a control group. The number of fights varied from 1 to 220 (mean 39.

Combined small-incision cataract surgery and trabeculectomy--technique and results.

In a prospective study 35 eyes of 25 patients with coexisting cataract and glaucoma underwent trabeculectomy, phacoemulsification and implantation of a folded polyHema intraocular lens through the trabeculectomy opening. Follow-up ranged from 6 to 27 months (mean 13.3).

Evaluation of 200 consecutive IOGEL 1103 capsular-bag lenses implanted through a small incision.

We evaluated 200 consecutive IOGEL 1103 capsular bag intraocular lenses. We performed a 5 to 6 mm capsulorhexis and inserted the intraocular lens (IOL) through a 3.5 to 4.

[Effect of argon laser trabeculoplasty on unrestricted outflow of aqueous humor in eyes with simple glaucoma].

In this prospective study we used the oculopressions-tonometry (OPT) for determination of the aqueous humor outflow facility (C). 53 phacic eyes with glaucoma simplex were examined pre- and postoperatively. One hour after operation C decreased from 0.

Endothelial cell density and corneal pachometry after no-stitch, small-incision cataract surgery.

In a prospective study we used the change of central and peripheral (12 o'clock-position) corneal thickness (CT) after no-stitch small incision cataract surgery as a parameter of tissue traumatisation (33 eyes) and compared the values to a series of cases (32 eyes) with conventional 3.5 mm scleral step incision. In both groups the peripheral measurements showed a higher increase in corneal thickness than the central.

Long-term follow-up of argon laser trabeculoplasty in uncontrolled primary open-angle glaucoma. A study with standardized extensive preoperative treatment.

The long-term results of 180 degrees argon laser trabeculoplasty (ALT) were studied in 61 eyes of 43 patients with uncontrolled primary open-angle glaucoma [intraocular pressure (IOP) less than 22 mm Hg]. In order to enhance the relevance of this prospective study, only eyes that had not responded to medication despite standardized extensive therapy were followed up over an average period of 4.4 years [52.
