Purpose:

To evaluate the refractive and visual outcomes after new intracorneal ring (Keratacx 355°) implantation in patients with keratoconus.

Methods:

This study included 14 eyes with keratoconus who underwent intracorneal ring implantation surgery. The preoperative and 3-month postoperative of uncorrected (UDVA) and corrected (CDVA) distance visual acuity, corneal sphere and astigmatism and keratometry readings (using Oculus Pentacam HR) were measured.

Results:

Preoperative and postoperative UDVA, sphere, astigmatism, minimum (Kmin) and maximum keratometry (Kmax) were 0.98 ± 0.27 and 0.54 ± 0.26 LogMAR, -2.81 ± 3.03 and -0.08 ± 2.18 D, -4.35 ± 3.08 and -3.23 ± 1.77 D, 46.86 ± 3.74 and 43.17 ± 3.51 D, 51.41 ± 3.72 and 46.31 ± 3.85 D, respectively. There were statistically differences between preoperative and postoperative of these parameters (UDVA (P=0.001), sphere (P=0.043), astigmatism (P=0.023), Kmin (P=0.002) and Kmax (p=0.001)). CDVA had no any statistically difference

Conclusion:

It seems that this intracorneal stromal ring can be effective for keratoconus correction. Further studies with larger sample size are needed to confirm these results.
