Modern management of congenital cataracts which interfere with vision consists of early removal of the cataract and correction of the refractive error by contact lenses or glasses (Parks and Hiles, I967; Von Noorden, Ryan, and Maumenee, I970). Skiascopic postoperative refraction of aphakic infants cannot always be performed satisfactorily because the opening is sometimes small and irregular and...

purpose : to describe a distinctive pattern of induced higher order aberration (hoa) after lasik for mixed astigmatism case reports : wavefront-guided lasik with iris recognition and eye tracking (excimer laser: technolas 217z apt protocol microkeratome: moria cb) was performed in six eyes with moderate to high mixed astigmatism for a nominal optical zone of 6.3 mm. the patients were re-examine...

the term reflex epilepsy in reserved for a small subgroup o seizures that occur regularly in response to specific stimuli. our patient is a 20- year old male, who had pleasure, euphoria, loss of conciousness and generalized tonic- clonic convulstion when he watched tv since ten years. during puberty the patient that self-induced reflex epilepsy with photic stimulation, when watching tv or looki...

profound bradycardia during eye surgery is a potentially serious event. in clinical practice oculo-cardiac reflex (ocr) is most often encountered during squint surgery. the objective of this study was to assess the occurrence of ocr and prove the effect of ketamine as an induction drug and anticholinergic premedication (atropine) to prevent ocr. this study comprised 90 patients (aged 4-10 years...

PURPOSE To present the approach of using a scanning slit refractometer (the ARK 10000) in conjunction with a corneal topography system to guide customized corneal ablation. This diagnostic system is coupled with the Nidek EC-5000 system which combines scanning slit and a scanning small area ablation (1.0 mm) to perform a customized ablation. METHODS The ARK 10000 diagnostic system which conta...
