Abstract: CONTEXT: In contact lens-intolerant keratoconus patients, intrastromal placement of Intacs is becoming a promising new modality of treatment. AIMS: To study the safety and efficacy of implantation of microthin corneal inserts (Intacs) in Asian-Indian keratoconus patients. SETTINGS AND DESIGN: Retrospective interventional case series, in the cornea and refractive surgery service, at a tertiary care eye hospital in South India, between May 2006 and July 2007. MATERIALS AND METHODS: Intacs (Addition Technology, USA) were successfully implanted by mechanically creating tunnels, in 12 eyes of 12 keratoconus patients, who were contact lens-intolerant. The patients (mean age 25.58 years, nine male and three female) had a minimum follow-up of six months. Five patients had severe keratoconus (mean K > 53 D) and nine had central cones. RESULTS: All patients improved or retained visual acuity. The uncorrected visual acuity (UCVA) improved from a mean value of 0.06, (SD +/- 0.08) to 0.19 postoperatively (SD+/- 0.15) ( P = 0.01). The change in mean best corrected visual acuity (BCVA) was from 0.51, (SD +/- 0.24), to 0.69, (SD +/-0.00) ( P = 0.01) postoperatively. The average central keratometry reading was 52.55 D. The change in mean K from 52.84 to 49.16 and 49.15 at one and six months respectively, was statistically significant. We did not have any major intra- or early postoperative complications. Eight of 12 eyes became contact lens-tolerant post-surgery. CONCLUSION: The procedure of Intacs implantation appears to be safe and effective in a small group of Indian population at an intermediate follow-up.
