Methods: Retrospective, consecutive, noncomparative case series analyzes the visual and anatomical results after flap dislocation or avulsion, caused by trauma occurred at least 1 month after LASIK.

Results: A total of 37,315 eyes of 19,602 patients were reviewed.

Vitreous incarceration in sutured vs non-sutured sclerotomies after 25-gauge macular surgery.

Objectives: To study the patterns of vitreous incarceration in sutured vs non-sutured sclerotomies in patients subjected to 25-gauge macular surgery.

Methods: A prospective study of 135 eyes affected by epiretinal membrane or macular hole. Vitreal disposition was evaluated via ultrasound biomicroscopy (UBM) at the sclerotomy sites between 30 and 40 days after surgery, once the tamponade had completely disappeared.

Anvil-profiled penetrating keratoplasty: load resistance evaluation.

The aim of this study was to qualitatively evaluate the biomechanical load resistance of different surgical wound configurations (mushroom, zig-zag, anvil and conventional trephination) in penetrating keratoplasty (PK) by designing a 2D and a 3D finite-element biomechanical model of the cornea. A mathematical model of the human cornea was developed, and different geometric configurations for PK were designed. The internal pressure was raised until the wound misaligned; wound prolapse then occurred.

VITREOUS INCARCERATION IN SCLEROTOMIES AFTER VALVED 23-, 25-, OR 27-GAUGE AND NONVALVED 23- OR 25-GAUGE MACULAR SURGERY.

Purpose: To study the patterns of vitreous incarceration at sclerotomy sites by ultrasound biomicroscopy in patients subjected to valved or nonvalved small-gauge pars plana vitrectomy.

Methods: A prospective comparative study of 88 eyes affected by epiretinal membrane and macular hole. Patients were divided into four groups: valved or nonvalved 23-gauge (16 eyes each) and valved or nonvalved 25-gauge (20 eyes each); their vitreal disposition was compared by ultrasound biomicroscopy.

Three-dimensional mapping of the orientation of collagen corneal lamellae in healthy and keratoconic human corneas using SHG microscopy.

Keratoconus is an eye disorder that causes the cornea to take an abnormal conical shape, thus impairing its refractive functions and causing blindness. The late diagnosis of keratoconus is among the principal reasons for corneal surgical transplantation. This pathology is characterized by a reduced corneal stiffness in the region immediately below Bowman's membrane, probably due to a different lamellar organization, as suggested by previous studies.

Bifocal refractive corneal inlay implantation to improve near vision in emmetropic presbyopic patients.

Purpose: To evaluate the safety and effectiveness of the Flexivue Microlens corneal inlay for the improvement of near vision in emmetropic presbyopic patients.

Setting: Ophthalmology Department, Misericordia e Dolce Hospital, Prato, Italy.

Design: Prospective interventional case series.

An "All-laser" Endothelial Transplant.

The "all laser" assisted endothelial keratoplasty is a procedure that is performed with a femtosecond laser used to cut the donor tissue at an intended depth, and a near infrared diode laser to weld the corneal tissue. The proposed technique enables to reach the three main goals in endothelial keratoplasty: a precise control in the thickness of the donor tissue; its easy insertion in the recipient bed and a reduced risk of donor lenticule dislocation. The donor cornea thickness is measured in the surgery room with optical coherence tomography (OCT), in order to correctly design the donor tissue dimensions.

Capsule contraction syndrome with a microincision foldable hydrophilic acrylic intraocular lens: two case reports and review of the literature.

Here we present 2 cases of capsule contraction syndrome (CCS). In both cases, a hydrophilic acrylic Akreos MI60 (Bausch and Lomb) intraocular lens (IOL) was implanted in the capsular bag through microincision cataract surgery, and the literature on the subject is reviewed. Since CCS has been described after the implantation of every IOL type, it is unlikely that the Akreos MI60 chemical and physical properties may cause CCS.

Morphologic study of the cornea by in vivo confocal microscopy and optical coherence tomography after bifocal refractive corneal inlay implantation.

Purpose: To evaluate the biocompatibility of the Flexivue Microlens intracorneal inlay based on healing of corneal wounds and analysis of corneal structural features using in vivo confocal microscopy (IVCM) and anterior segment optical coherence tomography (AS-OCT).

Setting: Ophthalmology Department, Misericordia e Dolce Hospital, Prato, Italy.

Design: Case series.

Improving Boston type 1 keratoprosthesis procedure: one-touch femtosecond-assisted preparation and centration of donor carrier tissue.

Purpose: We describe a technique to avoid decentration of the visual axis of the Boston type 1 keratoprosthesis (Kpro), performing 2 concentric trephinations with femtosecond laser.

Methods: Two concentric side cuts were performed in a donor cornea using the 150-kHz Intralase FS laser. Within the same applanation procedure, an 8.

Treatment of macular edema because of occlusive vasculitis with bevacizumab (avastin): efficacy of three consecutive monthly injections.

Purpose: To report the efficacy of intravitreal bevacizumab, administered in a series of three monthly injections followed by a period of observation, in the treatment of cystoid macular edema because of occlusive vasculitis.

Methods: This is a retrospective review of 13 consecutive eyes of 13 patients with cystoid macular edema because of occlusive vasculitis, which had been unresponsive to other medications and were treated with intravitreal bevacizumab (1.25 mg).

Phacoemulsificator and sterile drapes contamination during cataract surgery: a microbiological study.

Purpose: To determine the microbial contamination of the irrigating fluids at the time of phacoemulsification after the use of topical povidone-iodine and antibiotics prophylaxis.

Methods: A total of 119 patients undergoing cataract surgery were enrolled in this prospective study. All patients received 5 mg/mL levofloxacin starting from the day prior to surgery and topical and 5% povidone-iodine drops starting from 30 minutes before the surgery.

Growth of congenital malignant teratoid medulloepithelioma of the ciliary body: a case study.

The purpose of this study was to describe the growth pattern of congenital malignant teratoid medulloepithelioma of the ciliary body by reporting clinical and imaging findings with pathological correlation. An 11-month-old little girl presented with a whitish-pink iris mass in the right eye resulting from a small ciliary body mass consistent with medulloepithelioma at both clinical and computed tomography (CT) findings. At CT, the lesion showed heterogeneous attenuation, without intraocular calcifications.

Clinical and ultrasound biomicroscopic features in iris melanocytoma.

The clinical and ultrasound biomicroscopic features of two cases of iris melanocytoma are evaluated. On ultrasound biomicroscopy examination, iris melanocytoma appears as a highly reflective nodular mass with a smooth or irregular surface and sharp and well-defined edges. Ultrasound biomicroscopy also allows clear visualization and measurement of the tumors.

A 48-year-old man presented with hyphema, iridocyclitis, iridophacodonesis, and maculopathy after a contusive trauma. Ultrasound biomicroscopy identified a 90-degree cyclodialysis cleft with severe damage of the zonular fibers. Echographic B-scan examination revealed intravitreal hemorrhage and a 360-degree choroidal detachment.
