Influence of a Therapeutic Soft Contact Lens on Epithelial Healing, Visual Recovery, Haze, and Pain After Photorefractive Keratectomy.

Objectives: To examine the influence of a therapeutic soft contact lens (TSCL) after alcohol-assisted photorefractive keratectomy (PRK) on visual recovery, epithelial closure, pain perception, and haze formation.

Methods: Prospective, randomized, single-center, contralateral eye, patient-masked study. Same surgeon treated 15 patients with bilateral PRK using a Vidaurri Fluid Retention Ring (Katena) with 8.

Evaluation of epithelial integrity with various transepithelial corneal cross-linking protocols for treatment of keratoconus.

Purpose. Corneal collagen cross-linking (CXL) has been demonstrated to stiffen cornea and halt progression of ectasia. The original protocol requires debridement of central corneal epithelium to facilitate diffusion of a riboflavin solution to stroma.

Inflammatory response in the anterior chamber after implantation of an angle-supported lens in phakic myopic eyes.

Purpose. To evaluate the inflammatory reaction after implantation of an angle-supported foldable acrylic anterior chamber IOL for myopia correction over time. Methods.

Influence of corneal cross-linking for keratoconus on several objective parameters of dry eye.

Purpose: To evaluate the potential influence of corneal cross-linking (CXL) with ultraviolet-A light and riboflavin in keratoconic eyes on several objective parameters of dry eye syndrome.

Methods: This prospective single center study included 30 consecutive eyes of 16 patients that underwent CXL with riboflavin and ultraviolet-A treatment (epithelial removal, 30 minutes soaking with riboflavin, 30 minutes of illumination with 365 nm, 3 mW/cm(2), 5 cm distance). Several dry eye syndrome parameters were evaluated preoperatively and 3 and 6 months after the procedure: intra-individual comparison of fluorescein and Rose bengal staining, height of tear film meniscus, and tear film break-up time.

Keratectasia after treating presbyopia with INTRACOR followed by SUPRACOR enhancement.

Purpose: To report a case of unilateral keratectasia after INTRACOR, which was followed by an additional excimer LASIK enhancement with a new presbyopia-correcting ablation profile.

Methods: The non-dominant eye of a 49-year-old man with emmetropia was treated with the INTRACOR procedure using the Technolas femtosecond laser (Technolas Perfect Vision GmbH, Munich, Germany) for presbyopia. Neither eye had risk factors for keratectasia.

Aspheric wavefront-guided versus wavefront-guided LASIK for myopic astigmatism with the Technolas 217z100 excimer laser.

Purpose: To compare clinical outcomes of wavefront-guided LASIK with and without aspheric compensation in myopic eyes.

Methods: In this observational, single-center study, 134 eyes were treated using an aspheric module in combination with wavefront-guided profiles (PTA-algorithm) and compared to 146 eyes treated with the predecessor wavefront-guided software (APT) that has no aspheric compensation. All treatment plans included the Rochester nomogram that accounts for the preoperative manifest refraction and interaction of higher order aberrations.

Hypermotility of an iris-fixated anterior chamber phakic intraocular lens due to nontraumatic iris laxity.

Purpose: Permanent immovability of phakic intraocular lenses (pIOLs) for the correction of high myopia is crucial in avoiding injury to the corneal endothelium and maintaining visual acuity. Unstable position of iris-fixated pIOLs due to traumatic or nontraumatic disenclavation of the haptic has been described previously.

Methods And Results: We report a different mechanism of repeated excessive implant motility in both eyes of a young woman who developed late nontraumatic elongation of the iris fibers to which an iris-claw pIOL was fixated.

Effect of repositioning or discarding the epithelial flap in laser-assisted subepithelial keratectomy and epithelial laser in situ keratomileusis.

Purpose: To evaluate the influence of the epithelial flap after epithelial laser in situ keratomileusis (epi-LASIK) and laser-assisted subepithelial keratectomy (LASEK) to correct low to moderate ametropia on visual recovery, epithelial closure, pain, and haze formation.

Setting: Zentrum für Refraktive Chirurgie, Augenabteilung am St. Franziskus Hospital, Münster, Germany.

Influence of mydriatic eye drops on wavefront sensing with the Zywave aberrometer.

Purpose: To investigate a potential influence of mydriatic eye drops on wavefront sensing with the Zywave aberrometer (Technolas Perfect Vision) in terms of predicted phoropter refraction (PPR) and higher order aberrations (HOA).

Methods: In this prospective study, 200 myopic eyes were measured in miosis and pharmacologically induced mydriasis with an aberrometer and automated refraction. One hundred eyes were dilated with tropicamide 0.
