Endolacrimal KTP Laser–Assisted Dacryocystorhinostomy

Abstract

The success rate of 83% achieved with KTP laser-assisted dacryocystorhinostomy, using miniendoscopes for lacrimal endoscopy to visualize the exact site of obstruction, is better compared with that of prior studies without the use of miniendoscopes (with success rates of 47%-85%). The advantages of this technique are that it is a minimally invasive procedure, requires a short operating time, and avoids use of an external incision.

Insertion of Double Bicanalicular Silicone Tubes after Endonasal Dacryocystorhinostomy in Lacrimal Canalicular Stenosis: A 10-Year Experience

“…The use of a Hopkins endoscope (0°, Ø 0.89 mm, Storz) could assist better diagnosis. The success rate achieved by the Hofmann laserassisted DCR, using miniendoscopes for lacrimal endoscopy to visualize the exact site of obstruction, is promising (success rate of canal [and canalicular lacrimal stenoses]: 83%) [15] . The more complex and invasive conjunctival dacryocystorhinostomy with insertion of tubes has remained for several years an alternative to stents of the canaliculi [16,17] .…”

Thulium Laser Dacryocystorhinostomy for Symptomatic Epiphora

“…9 The recent advent of the portable Thulium laser provides a less expensive and portable option to the YAG or KTP laser. The 2.0 micron wavelength of the Thulium laser is almost identical to the Holmium laser, which is well known for its sutability for resection.…”

Use of endocanalicular dacryocystorhinostomy with multidiode laser in children

“…Woog et al [16] summarized the lasers used for endocanalicular laser dacryocystorhinostomy, and reported success rates ranging from 46% to 85%. The lasers used in endocanalicular laser dacryocystorhinostomy include argon, potassium titanyl phosphate (KTP):YAG, Holmium:YAG, Neodymium:YAG, and multidiode lasers [17][18][19][20][21][22]12].…”
