Purpose: Glaucoma following penetrating keratoplasty (PK) continues to be a serious problem that may ultimately become sight threatening. Knowledge of the risk factors for development of glaucoma following PK, such as preexisting glaucoma, pseudophakia, aphakia, and previous PK, can limit the occurrence and improve the outcome of the keratoplasty. The management of postkeratoplasty (Post-PK) gl...

Because two similar transscleral cyclophotocoagulation diode lasers with identical power & duration settings induced significantly different postoperative inflammation, we wanted to compare the real output of both lasers. Using a Power/Energy Meter (Fieldmaster) we compared the output of the two lasers (the Iridis [Quantel Medical] and the Iris Medical [OcuLight SLx]) at different energy levels...

NOVEMBER/DECEMBER 2011 CATARACT & REFRACTIVE SURGERY TODAY 35 E ndoscopic cyclophotocoagulation (ECP) involves laser ablation of the ciliary body epithelium under direct endoscopic visualization. The result is a lowering of IOP through a decrease in the production of aqueous humor. ECP can effectively treat most types of glaucoma. Often combined with phacoemulsification, ECP has been proven saf...

The newly patented MicroPulse P3 (MP3) device (Iridex) provides the surgeon a very safe and efficacious solution to treating glaucoma utilizing Iridex’s proprietary MicroPulse technology. While sharing similarities to G-Probe (Iridex), the primary advantage is the MP3 provides a kinder, gentler approach with identical efficacy yet improved safety profile.1 I have had the opportunity to be invol...

PURPOSE To compare the results of intraocular pressure (IOP) reduction by 3 treatment modalities, (a) glaucoma tube implants, (b) noncontact YAG laser cyclophotocoagulation (cycloYAG), and (c) contact transscleral diode laser cyclophotocoagulation (cyclodiode), in cases of advanced glaucoma refractory to alternative treatments. METHODS A consecutive group of 45 eyes that received cycloYAG wer...

Cycloablation is a destructive procedure used to decrease the intra-ocular pressure (IOP) trough the ablation of the ciliary body that produces aqueous humour. Many destructive techniques, including diathermy, cryotherapy, ultrasounds, beta irradiation, and laser photocoagulation have been employed with a wide range of results and side effects. Although all above techniques can effectively dest...
