PURPOSE OF REVIEW The use of Intacs as a therapeutic modality in contact lens intolerant patients with mild to moderate keratoconus is increasingly gaining acceptance in the ophthalmic community. RECENT FINDINGS During the past year we have gleaned significant new information about patients who are appropriate candidates, the location and relative placement of segment sizes and long-term safe...

Purpose. To evaluate surgically induced astigmatism (SIA) and the average corneal power change in symmetric intrastromal corneal ring segment (ICRS) implantation. Methods. The study included 34 eyes of 34 keratoconus patients who underwent symmetric Intacs SK ICRS implantation. The corneal pocket incision meridian was the preoperative steep meridian. Corneal power data were obtained before and ...

A 42-year-old man had Intacs (Addition Technology Inc.) implantation for early pellucid marginal degeneration (PMD). Two Intacs segments (0.45 mm thickness) were inserted uneventfully in the fashion typically used for low myopia correction (nasal-temporal). Eleven months after the procedure, the uncorrected visual acuity was 20/200, compared with counting fingers preoperatively, while the best ...

PURPOSE The objective of this study is to describe the authors' results with intrastromal corneal ring segments (Intacs) and a new variation of lamellar keratoplasty, termed intralamellar keratoplasty (ILK), for the treatment of keratoconus (KCN) and post-laser-assisted in situ keratomileusis (LASIK) ectasia. METHODS A retrospective review of contact lens-intolerant KCN and post-LASIK ectasia...

PURPOSE To evaluate the efficacy of single-segment Intacs and compare with double-segment Intacs in subjects with post-LASIK ectasia and keratoconus. DESIGN Retrospective comparative analysis. METHODS setting: Boxer Wachler Vision Institute, Beverly Hills, California, USA. study population: Thirty-seven eyes of 28 patients with keratoconus and post-LASIK ectasia classified into two groups: ...

PURPOSE To determine the efficacy of INTACS insertion using a femtosecond laser in the treatment of keratoconus and to compare it to the technique using a mechanical spreader. METHODS INTACS were inserted in 10 eyes using the mechanical spreader to create the channels and subsequently on another 20 eyes using the femtosecond laser. Uncorrected (UCVA) and best spectacle-corrected visual acuity...

PURPOSE To assess the changes in visual acuity and topographic indices after implantation of single-segment Intacs. METHODS Forty-two keratoconic eyes received Femtosecond-assisted single-segment Intacs. Uncorrected distance visual acuity (UDVA) and best spectacle corrected visual acuity (BSCVA), refractive error, keratometry (K1, K2, Km, and KMax.), and seven Pentacam measured topographical ...

purpose: to assess the efficacy of intrastromal rings for management of keratoconus (kcn). methods: this prospective non comparative case series includes 14 eyes of 11 contact lens intolerant patients with kcn. corneal thickness of at least 450 m at the site of segment insertion was required for enrollment. uncorrected visual acuity (ucva), best corrected visual acuity (bcva), refraction, pachy...

Purpose: To evaluate the efficacy of the combined treatment of Intacs SK (Severe keratoconus) and corneal collagen crosslinking in the management of advanced keratoconus (KC). Setting: Private laser center, Haifa, Israel. Affiliated to Hadassah Hospital, Jerusalem. Methods: This is a retrospective study. Intacs SK were implanted using manual technique in eyes with moderate-tosevere keratoconus ...
