purpose: to compare clear corneal incision and scleral tunnel incision in terms of intraocular pressure (iop), post-operative inflammation, induced astigmatism, and corneal edema in phacoemulcification. methods: this non-controlled clinical trial was conducted on 78 eyes with senile cataract. a clear corneal incision was made in 40 eyes and a scleral tunnel incision was made in 38 eyes. all eye...

OBJECTIVE To determine the relation between retinal tears and scleral ectasia. DESIGN Prospective study. SETTING University-based referral practice in Montreal. PATIENTS Fifty-seven consecutive patients with primary rhegmatogenous retinal detachments undergoing scleral buckling surgery. Patients with a history of trauma or previous cryotherapy, laser treatment or other vitreoretinal proce...

BACKGROUND Partial thickness sclerectomy is the most commonly employed scleral shortening technique used in conjunction with pars plana vitrectomy in the repair of myopia-associated macular holes in patients with staphyloma. Recently, scleral shortening induced through scleral invagination has been advocated as an adjunct in retinal translocation surgery. OBJECTIVE To determine whether a corr...

PURPOSE To delineate three-dimensionally the anterior and posterior surfaces of the lamina cribrosa, scleral flange, and peripapillary sclera, to determine the position and thickness of these structures within digital three-dimensional (3-D) reconstructions of the monkey optic nerve head (ONH). METHODS The trephinated ONH and peripapillary sclera from both eyes of three monkeys with early gla...

To characterize the material properties of posterior and peripapillary sclera from human donors, and to investigate the macro- and micro-scale strains as potential control mechanisms governing mechanical homeostasis. Posterior scleral shells from 9 human donors aged 57-90 years were subjected to IOP elevations from 5 to 45mmHg and the resulting full-field displacements were recorded using laser...

This case series examines the magnitude and regional variation in scleral lens–induced corneal edema postradial keratotomy (RK) eyes. Scheimpflug imaging was used to measure thickness across central 6 mm before after lens wear nine post-RK eyes (median age 64 years). Variations were examined as a function of distance from center (six 0.5-mm annuli) 0° 360°. The median 2.19% (interquartile range...

A scleral contact lens lies on the sclera, not cornea, which differs from a rigid gas permeable (RGP) lens, and has shown successful clinical outcomes in patients unable to tolerate glasses or RGP lenses because of severely deformed cornea. In addition, forms tear film between cornea that stabilizes ocular surface could be useful therapeutic option. The mini-scleral is option for visual improve...
