Comparative evaluation of diode laser ... - BMC Ophthalmology

The present study suggests that diode laser photocoagulation brings about a faster quantitative and qualitative visual recovery in comparison to argon green laser in eyes with central serous retinopathy. The main aim of performing laser photocoagulation in eyes with CSR is to hasten resolution and this is better fulfilled by diode laser.

Diode Laser Cyclophotocoagulation - Glaucoma Today

Effective laser treatment of the ciliary processes and ciliary body reduces the inflow of aqueous humor and, thus, decreases IOP—similar to the effect of several types of glaucoma medications. The laser treatment can be applied to an intact eye through the anterior sclera with continuous-wave red and diode near-infrared lasers (transscleral ...

In addition, an intense diode laser may cause photovaporization, and the exploding effect may lead to ICL displacement. Thus, the range and diode power of the laser should be considered preoperatively when performing TSCP in patients with both an IOL and ICL. Furthermore, it would seem necessary to avoid the direction of pupil displacement.

Diode Laser Uses in the General Practice - Dentistry Today

Research shows that 810-nm lasers have better coagulation, while 980-nm lasers cut and result in a smaller zone of necrosis. 3 The difference is negligible when you are talking about a difference of 1 to 2 cells and is thus not really a selling feature of a 980-nm laser over an 810-nm one (this may be more of a marketing feature).

Diode Cyclophotocoagulation (CPC) - Glaucoma Associates of Texas

Diode cyclophotocoagulation is an outpatient procedure. The patient receives a peribulbar block (anesthesia around the eye) prior to the laser. The laser, performed by your ophthalmic surgeon, takes 20 to 30 minutes and will require use of postoperative drops to decrease inflammation in the eye. Most patients have minimal postoperative pain.
