METHODS: Consecutive patients with medically controlled OAG and visually significant cataracts were treated with ECP and cataract extraction (study group) or cataract extraction alone (control group). The groups were matched in age and baseline intraocular pressure (IOP). The main outcome measures were the change in IOP and number of glaucoma medications. Secondary measures included visual acui...

Objective: To determine the corneal problems faced during and after phacoemulsification (phaco) as a beginner of phaco surgeries Methodology: Corneal problems in 100 cases of phaco were retrospectively analysed. Those cases with nuclei +3 / above and those who were operated in camps were excluded. Phaco-chop technique was used in 80% of cases. Average duration of surgery was 20 minutes Results:...

In this study we evaluate the visual outcomes, safety, efficacy, and stability of implanting of second sulcus intraocular lens (IOL) to correct unsatisfied ametropic patients after phacoemulsification. Methods. Retrospective study of 15 eyes (15 patients) underwent secondary intraocular lens implanted into the ciliary sulcus. The IOL used was a Sensar IOL three-piece foldable hydrophobic acryli...

This paper applies the direct digital frequency synthesis technology (DDS) to build a controllable variable frequency and waveforms of the bio-diesel fuel phacoemulsification system. The optimal operating parameters of phacoemulsification system are studied by orthogonal experiment. In the experiment, the ultrasonic frequency, waveform, power and process time are changed to study the stability ...

AIM To review retrospectively 74 consecutive cases of combined phacoemulsification and transpupillary drainage of silicone oil. METHODS Candidate patients for intraocular silicone oil removal and cataract extraction underwent combined phacoemulsification and transpupillary drainage of silicone oil through a planned posterior capsulorrhexis and without the use of a pars plana infusion line. ...

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...
