Purpose: To compare the short term effects of bevacizumab and ranibizumab injections on the regression of corneal neovascularization (NV).

Methods: Sixteen eyes of 16 patients with corneal NV were randomly assigned for an injection with 2.5 mg of bevacizumab (group 1, n = 8) or 1 mg of ranibizumab (group 2, n = 8) through subconjunctival and intrastromal routes.

Purpose: To compare corneal pachymetry assessment using slit scanning imaging (Orbscan), rotating Scheimpflug imaging (Pentacam), dual Scheimpflug system (Galilei), and ultrasound pachymetry in normal and post-femtosecond (FS) laser in situ keratomileusis (LASIK) eyes.

Methods: Sixty eyes of 60 patients were enrolled for this study, which consisted of 30 unoperated eyes (normal corneas) and 30 eyes after FS-LASIK (post-LASIK corneas). Central corneal thickness was measured sequentially using Orbscan II, Pentacam, Galilei, and ultrasound pachymetry, and the average value of measurements obtained by the 4 different methods were compared in each group.

The authors report using double-needle cataract extraction in the course of triple surgery and describe the usefulness of a double-needle technique. Before penetrating preparation of the recipient cornea, two straight double-arm 10-0 Prolene needles (Ethicon, Edinburgh, Scotland) were inserted in parallel on the recipient corneal bed transcorneally immediately anterior to the iris. The use of two needles stabilized the iris plane and offset positive vitreous pressure during triple surgery, continuous curvilinear capsulorrhexis, phacoemulsification, irrigation, and aspiration, allowing the safe implantation of an intraocular lens in the bag in an open-sky state.

Purpose: To report successful vision restoration after lamellar keratectomy using a femtosecond (FS) laser in a patient with superficial corneal opacity that developed after an episode of epidemic keratoconjunctivitis.

Methods: A 19-year-old girl with corneal opacity in the left eye was referred to our department for treatment. The opacity was principally located within the superficial anterior cornea.

The authors report successful vision restoration after cataract surgery using a femtosecond laser in a patient with superficial corneal irregularity. A 62-year-old man with corneal irregularity and a cataract in the left eye was referred for treatment. The superficial corneal opacity causing the irregularity was mainly located within the superficial anterior cornea.

Purpose: To report on a patient who received an eccentrically designed lamellar keratolimbal allograft prepared using a femtosecond (FS) laser to preserve peripheral curvature.

Methods: A 19-year-old woman, with a pseudopterygium on the left eye resulting from dermoid excision about 11 years earlier, received an eccentric lamellar keratolimbal allograft in a procedure involving FS laser use. Corneal flaps of depths 280 and 400 mum and diameters 6.

Background And Objective: To evaluate the effect of femtosecond laser lamellar dissection on corneal endothelium ultrastructure and viability.

Materials And Methods: Newly enucleated porcine eyes (N = 32) were used. The eyes were divided into four groups and a 7.

Purpose: To describe a new surgical technique for a patient with cataract combined with corneal opacity.

Methods: This technique, femtosecond laser-assisted cataract surgery, was performed on a patient with a history of corneal opacity in both eyes from childhood. Because the patient had deep stromal corneal opacity, a corneal button 400-mum thick was made for lamellar keratoplasty while cataract surgery was performed simultaneously.

Purpose: To evaluate the effect of using femtosecond (FS) laser technology for penetrating keratoplasty (PK) in terms of corneal graft endothelial ultrastructure and viability in porcine eyes.

Methods: Thirty-two freshly enucleated porcine eyes were divided into 4 equal groups (n = 8): group 1, incomplete penetration using the FS laser (a 100 microm-depth from the endothelial side remained); group 2, complete penetration using the FS; group 3, trephination using a vacuum trephine until the aqueous humor appeared; group 4, no treatment (control group). For groups 1 and 2, side cuts were performed using a 60-kHz FS laser (IntraLase FS Laser, Abbot Medical Optics, Abbott Park, IL).

Purpose: The purpose of this study was to describe a new method of femtosecond (FS) laser-assisted corneal tattooing and to report the results of this method in a case series.

Methods: The study involved 6 eyes of 6 patients with total or partial corneal opacity. An FS laser was used for lamellar dissection and to make a side cut with a hinge, creating a corneal flap.

Purpose: To determine the anatomic cleavage planes produced by various epikeratomes in epithelial laser in situ keratomileusis (epi-LASIK).

Setting: Department of Ophthalmology, IIsan Paik Hospital, Goyang, Korea.

Methods: Sixteen eyes (8 patients) were included in this study.

A 43-year-old woman had laser in situ keratomileusis (LASIK) using the IntraLase femtosecond laser (IntraLASIK) to create 110 microm flaps. Despite uneventful flap formation, the flaps in both eyes were extremely thin, making it difficult to lift them. The flap in the right eye resembled an epi-LASIK epithelial flap.
