BACKGROUND Cataract surgery after penetratingkeratoplasty (PKP) is often challenging due to changes in the integrity of the cornea caused by PKP. For example, corneal endothelial cell (CEC) loss and corneal edema commonly occur after traditional phacoemulsification cataract surgery in patients that previously had successful PKP. Recent studies have reported that femtosecond laser-assisted catar...

To the Editor: Radial keratotomy (RK) can be effective in reducing low to moderate amounts of myopia. Occasionally, a patient will “under-respond” to the RK procedure and be left with significant residual myopia. The refractive surgeon may then be presented with a situation where the patient desires more myopic reduction, but the surgeon does not want to perform another RK (for fear of inducing...

OBJECTIVE To determine if a biodendrimer adhesive will seal a clear corneal cataract incision. DESIGN An experimental study in which 2.75-mm clear corneal cataract incisions were made in 8 human donor eyes. The corneas were mounted on an artificial anterior chamber. Leaking pressure was determined in 6 corneas. These corneas were then treated with adhesive and leaking pressure was again measu...

PURPOSE To investigate the effects of loss of osteopontin (OPN) in the healing of the injured cornea in mice. Cell culture study was also conducted to clarify the effects of OPN in fibroblast behaviors. METHODS Ocular fibroblasts from wild-type (WT) and OPN-null (KO) mice were used to study the role of OPN on cell behavior. The effect of the lack of OPN on corneal wound healing was evaluated ...

Platform presentation at 2011 ATACCC Conference, Fort Lauderdale FL, August 15-18,2011 Sealing Penetrating Eye Injuries Using Photoactivated Bonding A.J. Johnson, E.E. Verter, T. Gisel, P. Yang, R.W. Redmond, I.E. Kochevar Objective: To rapidly seal irregular-shaped penetrating wounds in cornea and sclera with lessscarring, better visual outcomes and reduced OR time requirement. Backgro...

To improve visual and refractive outcomes, microkeratome-assisted lamellar keratoplasty for the treatment of keratoconus (exchange of a 9.0-mm anterior recipient lamella with a 9.0-mm donor lamella, using a 200-μm head for the former and a 300-μm head for the latter) was modified by adding a 6.5-mm incomplete full-thickness incision in the recipient bed before suturing the donor graft in place....

Introduction Cataract surgery has undergone various advances since it was evolved from ancient couching to the modern phacoemulsification cataract surgery. Surgically induced astigmatism (SIA) remains one of the most common complications. The introduction of sutureless clear corneal incision has gained increasing popularity worldwide because it offers several advantages over the traditional sut...

an 8-month-old female thoroughbred foal was presented showing signs of colic. the foal was anxious,exhibiting signs of abdominal pain and distention. the foal had tachycardia (120 beats/min), tachypnea (40breaths/min). blood samples obtained for haematologic and serum biochemistry analysis that showed a pcvof 30% and a tpp of 70 g/l. the peritoneal fluid analysis revealed a clear fluid with mil...
