[Comparative study of treatment of the dry eye syndrome due to disturbances of the tear film lipid layer with lipid-containing tear substitutes].

Background: A deficiency in the tear film lipid layer is aetiological in about 80 % of the patients suffering from dry eye, which results in excessive evaporation (so-called hyperevaporative dry eye). The treatment with conventional artificial tears did not prove to be successful here. In this study the treatment with two tear substitutes containing lipids were set in contrast with each other.

[A new therapy concept for the treatment of dry eye--the usefulness of phospholipid liposomes].

Background: Most of the eye drops currently used replace only the aqueous phase of the tear film. But, due to the fact that, with approximately 80 % of the patients with a dry eye, a disturbance of the lipid phase is present, an approach for new treatment methods needed to be found. We examined a new therapy concept with an eye spray containing liposomes for the therapy of the "dry eye" in a long-term study.

Wavefront-supported photorefractive keratectomy: 12-month follow-up.

Purpose: To evaluate safety, efficacy, predictability, and stability of wavefront-supported photorefractive keratectomy (PRK) for correction of myopia and myopic astigmatism, with 12-month follow-up.

Methods: Thirty eyes of 23 patients with myopia less than -8.00 D (mean -3.

Topography-controlled excimer laser photorefractive keratectomy.

Purpose: To assess whether photorefractive keratectomy (PRK) controlled by videokeratography can successfully treat refractive errors in eyes with corneal irregularities and improve spectacle-corrected visual acuity.

Methods: In a prospective clinical study, PRK was performed in 10 eyes of 10 patients. Reason for surgery was irregular astigmatism after penetrating keratoplasty, corneal irregularity after corneal scarring, corneal astigmatism in keratoconus, and decentration after myopic and hyperopic PRK.
