Artificial iris devices: Benefits, limitations, and management of complications
In patients with major iris defects ineligible for pupilloplasties, the artificial iris allows functionally and esthetically satisfactory anterior segment reconstruction and should only be implanted in aphakic or pseudophakic eyes and placed in the posterior chamber to prevent secondary complications.
Postoperative astigmatism and rotational stability after Artisan toric phakic intraocular lens implantation
During the 6‐month follow-up, no significant rotation was observed after implantation of Artisan toric phakic IOLs to correct high ametropia and a sutureless sclerocorneal superior approach for phakIC IOL insertion resulted in moderate to low astigmatism.
Corneal penetration of fluoroquinolones: Aqueous humor concentrations after topical application of levofloxacin 0.5% and ofloxacin 0.3% eyedrops
The new fluoroquinolone, levofloxacin, is more soluble in water enabling the use of higher drug concentrations (0.5%) compared with other currently available fluoroquolone eyedrops ( 0.3%).
Prosthetic iris devices.
Since the first implant of a black iris diaphragm posterior chamber intraocular lens in 1994, advances in material and design technology over the last decade have led to advances in the prosthetic material, surgical technique, and instrumentation in the field of prosthetic iris implants.
Ultraviolet radiation absorption of intraocular lenses.
Intraocular lenses of different compositions have ultraviolet radiation absorption characteristics different from that of the crystalline lens.
Photo-Cell Device for Slit-Beam Adjustment to the Optical Axis of the Eye in Scheimpflug Photography
In the photographic documentation of lens findings according to Scheim-pflug’s principle, a good reproducibility of the camera adjustment to the patient’s eye is prerequisite for quantitative densitom
Investigations on the Influence of Oxyphenbutazone on Formation of Galactose-Induced Cataracts in Rats
The effect of oxyphenbutazone (5% and 10% Tanderil eye ointment) on formation and progress of galactose-induced cataracts was investigated in rats and OPB seemed to cause a slower progression of cataract progression.
Experimental cataracts in rats due to tryptophan-free diet
A Tryptophan-free diet induces posterior subcapsular cataracts and reversible corneal opacities in young Wistar rats and if tryptophan is restored to the diet after 24 days, new clear lens fibers are laid down again, indicating that the mechanism of protein synthesis has not been permanently damaged by tryptophilean-deficiency.
Effect of 8-methoxypsoralen on rat lens cations, membrane potential and protein levels.
Dramatic changes in the dry weight, soluble protein and calcium content of the lenses were apparent only after eight weeks from the start of treatment, and these changes coincided with the appearance of very large vacuoles in slit-lamp examinations of the eye.
