Factors affecting the decision for refractive surgery in patients with high degrees of ametropia.

Purpose: To evaluate reasons referred patients do not have refractive surgery.

Setting: University Eye Clinic, Department of Ophthalmology, Aarhus University Hospital, Aarhus, Denmark.

Design: Cross-sectional study.

Efficacy, safety, predictability, contrast sensitivity, and aberrations after femtosecond laser lenticule extraction.

Purpose: To compare femtosecond lenticule extraction and small-incision lenticule extraction to treat moderate to high myopia.

Setting: Department of Ophthalmology, Aarhus University Hospital, Aarhus, Denmark.

Design: Prospective clinical single-masked paired-eye study.

Subbasal nerve morphology, corneal sensation, and tear film evaluation after refractive femtosecond laser lenticule extraction.

Background: The purpose of this study was to compare corneal subbasal nerve morphology, corneal sensation, and tear film parameters after femtosecond lenticule extraction (FLEX) and small-incision lenticule extraction (SMILE).

Methods: A prospective, randomized, single-masked, paired-eye design clinical trial of 35 patients treated for moderate to high myopia with FLEX in one eye and SMILE in the other. In both techniques, an intrastromal lenticule was cut by a femtosecond laser and manually extracted.

Corneal resistance to shear force after UVA-riboflavin cross-linking.

Purpose: We evaluated whether UVA-riboflavin collagen cross-linking (CXL) increases transverse stromal shear moduli ex vivo, whether the shear moduli are greater in the anterior compared to the posterior stroma, and whether the shear moduli are affected by CXL.

Methods: The resistance to unidirectional transverse shear of human (n = 18) and porcine (n = 42) corneas was measured in a custom engineered biaxial biomechanical setup at different hydrations. The corneas were separated into untreated, riboflavin solution-treated, and CXL-treated groups.

Long-term outcomes of photorefractive keratectomy for low to high myopia: 13 to 19 years of follow-up.

Purpose: To evaluate long-term outcomes after photorefractive keratectomy (PRK).

Methods: A retrospective follow-up study of patients who received PRK at 5.0- to 6.

Artemisinin production and precursor ratio in full grown Artemisia annua L. plants subjected to external stress.

The concentration of the lifesaving antimalarial compound artemisinin (AN) in cultivated Artemisia annua (A. annua) plants is relatively low, and thus research in improving the content is important. In the present study, external stress was applied to adult plants of A.

Femtosecond (FS) laser vision correction procedure for moderate to high myopia: a prospective study of ReLEx(®) flex and comparison with a retrospective study of FS-laser in situ keratomileusis.

Purpose: To present our initial clinical experience with ReLEx(®) flex (ReLEx) for moderate to high myopia. We compare efficacy, safety and corneal higher-order aberrations after ReLEx with femtosecond laser in situ keratomileusis (FS-LASIK).

Methods: Prospective study of ReLEx compared with a retrospective study of FS-LASIK.

Corneal distribution of riboflavin prior to collagen cross-linking.

Purpose: To evaluate the distribution of riboflavin in the corneal stroma, under varying concentrations and application time.

Materials And Methods: In 54 porcine eyes, the central corneal epithelium was removed, and 0.035, 0.
