Accommodation-related changes in monochromatic aberrations of the human eye as a function of age.

Purpose: To investigate the relationship between accommodation and the optical aberrations of the whole human eye, as a function of age.

Methods: Sixty healthy subjects with spherical ametropia in the range +/-3 D, astigmatism less than 1 D, corrected visual acuity of 20/18 or better, and normal findings in an ophthalmic examination were enrolled. Subjects were divided into four groups, with age ranges of 19 to 29, 30 to 39, 40 to 49, and 50 to 60 years.

[ISO 9001-2000 certification for refractive laser treatment].

Purpose: To obtain ISO 9001-2000 certification for laser corneal refractive treatment, never before sought in Europe.

Material And Methods: The consulting firm Veritas led the certification process with the clinic's staff manager. This ISO norm is dedicated to the implementation of a quality management system.

Vitrectomy with endoscopy for management of retained lens fragments and/or posteriorly dislocated intraocular lens.

Purpose: To evaluate the advantages of vitrectomy combined with endoscopy for the management of retained lens fragments and/or posteriorly dislocated intraocular lens (IOL).

Methods: A consecutive series of 30 eyes with these complications treated by this technique was reviewed retrospectively. An endoscopic probe which incorporates a video channel, a fibreoptic light source, and a diode laser was used for visualization.

[Evaluating the results of surgery of choroidal neovessels].

Background: Subfoveal choroidal neovascularization has usually a poor visual prognosis. Submacular surgery has been advocated as an alternative treatment. Visual results of this recent surgical technique is under current clinical evaluation.

[Intrastromal thermokeratoplasty for correction of spherical hyperopia: a 1-year prospective study].

Thermokeratoplasty (TKP) is a new procedure for surgical correction of hyperopia. It uses controlled thermal burns of the peripheral cornea with a retractable cautery probe tip in a radial pattern up to a premarked optical central zone. The thermal effect shrinks the peripheral cornea and steepens the central cornea.

[Conjunctival epidermoid carcinoma and human immunodeficiency virus].

We describe the clinical and histopathological findings of a conjunctival squamous cell carcinoma occurring in a patient with acquired immunodeficiency syndrome (AIDS). The excisional biopsy specimen disclosed a papillar, well differentiated and mature squamous cell carcinoma with microinvasion. The biopsy was studied for the presence of Human papilloma virus DNA by using in situ hybridization but no signal was demonstrated in any part of the tumour.
