The use of femtosecond lasers has created an evolution in modern corneal and refractive surgery. With accuracy, safety, and repeatability, eye surgeons can utilize the femtosecond laser in almost all anterior refractive procedures; laser in situ keratomileusis (LASIK), small incision lenticule extraction (SMILE), penetrating keratoplasty (PKP), insertion of intracorneal ring segments, anterior ...

The human clinical manifestations of staphylococcic infections of the eyelids, conjunctiva, and cornea are discussed. The corneal lesions occurring during the course of staphylococcic infections of the lid develop after the disease has been present in the eyelid for several years, but are not always correlated with the degree of activity. The peripheral infiltrations and ulcerations either are ...

Uniformly severe corneal infections were produced in rabbits by intracorneal injection of a few viable Pseudomonas aeruginosa. The bacteria multiplied rapidly, and within 24 hr, about 10 million organisms were present. The numbers remained stable thereafter. Polymorphonuclear leukocytes (PMNs) began to infiltrate peripheral stroma 24 hr after inoculation. By 32 hr, ring-shaped dense accumulatio...

Two cases of corneal cysts are reported, one sclerocorneal and the other intracorneal. The two conditions differ in pathogenesis, appearance, course, and management.

PURPOSE We detected keratoconus cases with a significant potential for poor outcomes following intracorneal ring segment implantation (ICRS). We attempted to predict the potential of a case in terms of gain or loss of corrected distance visual acuity (CDVA). METHODS In this retrospective and prospective, consecutive, nonrandomized, multicentric study, 58 keratoconic eyes (aged 1756) were impl...

Custom high-resolution high-speed anterior segment spectral domain Optical Coherence Tomography (OCT) was used to characterize three-dimensionally (3-D) corneal topography in keratoconus before and after implantation of intracorneal ring segments (ICRS). Previously described acquisition protocols were followed to minimize the impact of the motions of the eye. The collected set of images was cor...

METHODS: This prospective non-comparative interventional case series comprised eight eyes of eight patients with high residual astigmatism after keratoplasty, who had Keraring® ICRS implantation aided by femtosecond laser (FL). We evaluated uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), refractive astigmatism and corneal maximum (Kmax) and minimum curvature (Kmin) at one...
