AIMS To determine whether topical anaesthesia in small incision self-sealing phacoemulsification cataract surgery provides comparable anaesthesia to sub-Tenon's infiltration. METHODS Thirty five patients undergoing small incision self-sealing phacoemulsification cataract surgery were allocated randomly to receive topical anaesthesia with 0.4% oxybuprocaine or sub-Tenon's infiltration with 2% ...

AIM To evaluate outcome of vitrectomy performed at the time of phacoemulsification complicated by intravitreal lens material. METHODS Clinical records associated with consecutive 8536 phacoemulsification procedures were reviewed retrospectively. RESULTS 17 (0.20%) eyes had a posterior capsule rupture with retained lens material in the vitreous cavity that required vitrectomy. Final visual a...

AIM The complications of intraocular silicone oil include emulsification, which may lead to vision-threatening disorders such as keratopathy, secondary glaucoma and retinopathy. The authors study the effect of mechanical energy from surgical instruments on the emulsification of silicone oil. METHODS Three different handpieces (phacofragmentation, phacoemulsification, high-speed vitrectomy) we...

PURPOSE To report the case of a patient who developed late capsular block syndrome and to review the current literature regarding this complication of phacoemulsification procedures. METHODS The literature was reviewed to summarize the diagnosis, classification, use of diagnostic aids, and the current treatments for this complication. RESULTS A 69-year-old patient complained of decreased vi...

PURPOSE This study was designed as a microbiologic survey of the fluids aspirated from the anterior chamber at the end of cataract extraction performed by phacoemulsification, and to correlate the contamination rate of the anterior chamber to the surgical technique used. METHODS One hundred and one consecutive patients (126 eyes) who underwent cataract extraction by phacoemulsification and po...

This study evaluated the surgical outcome and complications of phacoemulsification and the implantation of an acryl foldable intraocular lens (IOL) with a squared edge in dogs with cataracts. Thirty-two eyes from 26 dogs were examined. The mean follow up period was 75.9 days ranging from 23 to 226 days. The complications after phacoemulsification were posterior capsular opacity (PCO) around the...

AIM To assess the incidence of anterior chamber bacterial contamination during phacoemulsification surgery using an automated microbial detection system (BacT/Alert). METHODS Sixty-nine eyes of 60 patients who had uneventful phacoemulsification surgery, enrolled in this prospective study. No prophylactic topical or systemic antibiotics were used before surgery. After antisepsis with povidone-...

Purpose: To demonstrate an approach to the problems of cataract surgery in extensive iridoschisis Methods: Four eyes of 2 patients with extensive iridoschisis had cataract surgery by the same surgeon using the techniques that resembled techniques for phacoemulsification in intraoperative floppy iris syndrome (IFIS). We used low flow parameters on phacoemulsification, used super-cohesive ophthal...

Phacoemulsification in angle closure can be challenging. Many factors, including large lens, small pupil and a narrow working space in the anterior chamber, contribute towards an increased level of difficulty. Angle closure eyes are also often associated with increased risk of complications such as malignant glaucoma and suprachoroidal hemorrhage. For the inexperienced or the unsuspecting, phac...

Twenty-one dogs were used to study the effects of phacoemulsification and extracapsular lens removal on corneal endothelium and corneal thickness. Specular microscopy revealed preoperative cell morphology and cell densities similar to man. After surgery endothelial cell counts significantly decreased 22% (central) and 13% (periphery) with phacoemulsification and 34% (central) and 31% (periphery...
