Evaluation of the Accuracy of Two Marking Methods and the Novel toriCAM Application for Toric Intraocular Lens Alignment.

Purpose: To compare the accuracy of two common reference marking methods for toric intraocular lens alignment before and after using the novel toriCAM application.

Methods: In this prospective, randomized study, 22 participants were randomly allocated to two groups, either freehand or slit-lamp-assisted marking. Corneal markings at 0° and 180° were made using either method.

Prospective study on exclusive, nonsurgical strontium-/yttrium-90 irradiation of pterygia.

Purpose: Prospective study to evaluate consecutive treatment results and to demonstrate safety and efficacy of nonsurgical, exclusive strontium-/yttrium-90 beta-irradiation of nonoperated pterygia.

Patients And Methods: Between November 1999 and March 2002, 20 patients with 21 primary pterygia and six patients with recurrent pterygia after former surgery were treated with exclusive strontium-/yttrium-90 irradiation up to a total dose of 3,600 cGy (six fractions) and 4,800 cGy (eight fractions), respectively. All patients were referred from a single institution.
