Corneal wound healing after laser vision correction.

Any trauma can trigger a cascade of responses in tissues, with the purpose of safeguarding the integrity of the organ affected by the trauma and of preventing possible damage to nearby organs. Subsequently, the body tries to restore the function of the organ affected. The introduction of the excimer laser for keratorefractive surgery has changed the treatment landscape for correcting refractive errors, such as myopia, hyperopia, and astigmatism.

Under-air staining of the anterior capsule using Trypan blue with a 30 G needle.

The original technique of staining the anterior capsule of the lens with Trypan blue involves the injection of an air bubble in the anterior chamber. A drawback of this technique is the possible instability of the anterior chamber caused by the sudden exit of air when the dye is injected with the cannula through the side-port incision. Other staining techniques that use viscoelastic substances to increase the stability of the anterior chamber and to dose the injected dye have been described.

Comparison of macular thickness measurements between time-domain and spectral-domain optical coherence tomographies in eyes with and without macular abnormalities.

Purpose: To compare Stratus time-domain optical coherence tomography (OCT) with Cirrus spectral-domain HD-OCT for measuring macular thickness in eyes with and without macular abnormalities.

Methods: Seventy-five eyes of 48 patients were included in the study. Forty-one eyes of 29 patients had a normal macular thickness, and 34 eyes of 26 patients had an abnormal macular thickness.

Anti-vascular endothelial growth factor activity in the bevacizumab and triamcinolone acetonide combination for intravitreal use.

Purpose: To find out if the combination for intravitreal use of the antibody bevacizumab (AvastinTM; Genentech, Inc., San Francisco, CA) and triamcinolone acetonide (TA) (Kenacort; Bristol-Myers Squibb, Anagni, Italy) could affect over time the anti -vascular endothelial growth factor (VEGF) activity of bevacizumab.

Methods: Two different combined preparations were obtained, drawing up together 1.

Excimer laser-assisted lamellar keratoplasty for the surgical treatment of keratoconus.

Purpose: To evaluate the anatomical and functional results of excimer laser-assisted lamellar keratoplasty (ELLK) in keratoconus patients.

Setting: Eye Clinic, University of L'Aquila, L'Aquila, Italy.

Methods: This prospective case series comprised patients with keratoconus who had ELLK and were examined preoperatively and 3, 6, 12, and 24 months postoperatively.

Comparison of optical low coherence reflectometry and ultrasound pachymetry in the measurement of central corneal thickness before and after photorefractive keratectomy.

Purpose: To compare an ultrasound pachymeter with an optical low coherence reflectometry (OLCR) pachymeter for measuring pre- and postoperative central corneal thickness of patients undergoing photorefractive keratectomy (PRK).

Methods: In a prospective, noncomparative, interventional study, 48 myopic eyes (mean manifest refractive spherical equivalent: -4.93 +/- 2.

Immunotherapy with imiquimod 5% cream for eyelid nodular basal cell carcinoma.

Purpose: To evaluate the efficacy and safety of topical imiquimod 5% cream for the treatment of eyelid basal cell carcinoma.

Design: Two interventional case reports.

Methods: Imiquimod 5% cream was applied topically once daily, 3 days a week for 8 to 12 weeks, in two patients affected by eyelid nodular basal cell carcinoma.

Pre-excimer laser and post-excimer laser refractive surgery measurements of scotopic pupil diameter using 2 pupillometers.

Purpose: To compare a digital infrared pupillometer with a handheld light amplification pupillometer for measuring scotopic pupil size and to evaluate if the postoperative refractive changes of the cornea can influence pupil measurements.

Design: Prospective noncomparative interventional case series.

Participants: One hundred eyes, 50 myopic (mean spherical equivalent [SE] refraction [+/- standard deviation], -4.
