Supplemental intravitreal gas injection was used in the early postoperative period in an attempt to achieve long term retinal reattachment in 11 cases of failed scleral buckling surgery. Success was dependent on the presence of a correctly placed scleral buckle underlying all breaks. Surgical revision was thereby avoided in these patients. However, when the scleral buckle was inadequate the tec...

Mitomycin (MMC) has been associated with a variety of complications, including corneoscleral melt. We report the successful repair of a scleral melt with a partial thickness autologous scleral graft of the scleral melting. A 55-year-old male patient underwent pterygium resection surgery and intraoperative MMC application. The patient developed a deep melting area that almost reached the choroid...

PURPOSE To report the outcomes of surgical refixation of posteriorly dislocated intraocular lens (IOL) using scleral-tuck method, and to compare the "scleral groove" and the "scleral flap" techniques used. STUDY DESIGN Single-center, retrospective, interventional, comparative study. METHODS Medical records of patients undergoing closed globe scleral refixation of posteriorly dislocated post...

The present study aimed to investigate the efficacy of tailored treatment for the management of scleral necrosis following pterygium surgery. A series of nine cases of scleral necrosis following pterygium excision between September 2009 and September 2012 were included. In cases where ischemia was the cause of scleral necrosis, Tenon's membrane covering (TMC) surgery was performed. For cases wi...

in this study, the formation of different parts of a cup during deep drawing process has been investigated analytically using the geometrical relationships. for a given punch travel, the effects of the bending angle, and those of the die and shoulder radii on the flange and die shoulder strains were examined. in addition, different components of the deformation force were calculated and the pun...

OBJECTIVE To present a comprehensive review of current and historical literature on scleral lenses. METHODS A comprehensive search of several databases from each database's earliest inception to May 23, 2014 was conducted by an experienced librarian with input from the author to locate articles related to scleral lens design, fabrication, prescription, and management. RESULTS A total of 899...

Scleral fixation of intraocular lenses (IOLs) can be performed under the protection of a scleral flap. A variation of this technique uses a scleral tunnel for suture fixation to the eye. Passage of a double-armed suture through the roof of the scleral tunnel with subsequent retrieval of the suture ends through the external incision for tying facilitates scleral fixation. This modification offer...

BACKGROUND Scleral buckling is still a common procedure to repair rhematogenous retinal detachment, and acute or chronic infection of the scleral explant is rare. We report an intractable case of acute scleral explant infection by Pseudomonas aeruginosa. CASE A 36-year-old man suffered from acute scleral explant infection by P. aeruginosa forty-eight hours after scleral buckling for rhegmatog...

An experimental study has been conducted on the penetration of silicone rubbers and human skin in vivo by sharp-tipped and flat-bottomed cylindrical punches. A penetrometer was developed to measure the penetration of human skin in vivo, while a conventional screw-driven testing machine was used to penetrate the silicone rubbers. The experiments reveal that the penetration mechanism of a soft so...
