Area of Science:

  • Ophthalmology
  • Laser Surgery

Background:

  • Peripheral iridotomy is a common ophthalmic procedure.
  • Neodymium:YAG (Nd:YAG) laser technology has gained popularity for this intervention.

Purpose of the Study:

  • To evaluate the safety and efficacy of Nd:YAG laser peripheral iridotomy.
  • To compare Nd:YAG laser iridotomy with traditional Argon laser iridotomy.

Main Methods:

  • Utilizing Nd:YAG laser with energy levels of 2-8 mJ per shot.
  • Employing 1-3 shots per treatment session for iridotomy.
  • Observing patient outcomes and complications post-procedure.

Main Results:

  • Most irides were penetrated in a single session.
  • Nd:YAG laser iridotomies demonstrated low closure rates, except in cases of intraocular inflammation.
  • Hemorrhage was common, but clinically significant hyphema was rare.
  • Corneal or lenticular damage was extremely rare.

Conclusions:

  • Nd:YAG laser iridotomy is a safe and effective procedure for peripheral iridotomy.
  • It presents a viable alternative to Argon laser iridotomy in selected patients.
  • Further long-term studies are needed to fully establish its long-term efficacy.
