To the Editor: Femtosecond laser platforms used for cataract surgery are integrated with anterior-segment optical coherence tomography (AS-OCT), allowing for real-time imaging and measurement of the cornea, possibly leading to more precise arcuate keratotomies.1 The femtosecond laser permits creation of either anterior penetrating incisions or intrastromal incisions. The advantages of intrastro...

Silicate nanoparticle; Corneal neovascularisation; Vascular endothelial growth factor Abstract Corneal neo-vascularisation (NV) is a major sight-threatening condition and is caused by infections, degenerative disorders, inflammation and long-time contact lens wear. Corneal NV occurs when the balance between angiogenic and antiangiogenic factors is tipped towards angiogenic molecules. The abnorm...

Several surgical strategies have been proposed to improve visual function in patients with keratoconus who become contact lens intolerant1,2. In mild-tomoderate keratoconus, when the central cornea remains clear, intrastromal corneal ring segments (ICRS), and phakic intraocular lenses (PIOLs) may provide enough BSCVA, and sometimes uncorrected visual acuity (UCVA), to postpone and sometimes avo...

A 49-year-old man with an uncorrected visual acuity (UCVA) of 20 / 1000, a best spectacle-corrected visual acuity (BSCVA) of 20 / 400, keratometric readings of K1 = 59.88 × 82° / K2 = 45.88 × 172°, and an inferior steepening that was consistent with keratoconus in his left eye was treated with clear-cornea phacoemulsification and an intraocular lens (IOL) implantation after insertion of kerarin...

BACKGROUND Fungal keratitis has been rarely reported following intracorneal ring segment (ICRS) inmplantation. This paper aims to report a case of fungal keratitis with aspergillus fumigatus following ICRS implantation for correction of keratoconus. METHODS A retrospective chart review was done. Data including demographics, clinical history and presentation, microbiological analysis as well a...

PURPOSE The eighth annual survey was carried out by mail in February 2000 to investigate the current trends in cataract and refractive surgery in Japan. RESPONDENTS Questionnaires were sent to 930 ophthalmologist members of the Japanese Society of Cataract and Refractive Surgery. Data received from 457 (49.1%) of the recipients were cross-analyzed and compared with those from the previous sur...
