Purpose:
To evaluate the clinical outcomes of the new intrastromal corneal ring segment (Intacs SK) in treatment of moderate and severe cases of keratoconus.
Setting:
: Al Salam international Hospital , Kuwait
Methods:
Thirteen eyes of 12 patients with moderate and severe keratoconus were treated with Intacs SK. The uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA), manifest sphere and cylinder, spherical equivalent, and keratometry (K) readings were measured preoperatively and at 1, 6, and 12 months postoperatively.
Results:
There was significant improvement of UDVA, CDVA, manifest sphere and cylinder, spherical equivalent, and K readings (P < 0.05) at 1 year postoperative. The mean UCDV improved from 0.08 ± 0.03 to 0.19 ± 0.07 (P < 0.001); the mean CDVA improved from 0.28 ± 0.13 to 0.52 ± 0.13 (P = 0.001); the mean sphere and cylinder changed from −7.96 ± 3.74 and −6.51 ± 3.29, respectively, to −3.80 ± 2.3 and −2.32 ± 1.34 (P < 0.001); the mean spherical equivalent changed from −10.77 ± 3.97 to −5.02 ± 2.44 (P < 0.001); and the mean minimum and maximum K values changed from 50.88 ± 5.27 and 55.76 ± 3.97, respectively, to 46.78 ± 4.7 and 49.11 ± 3.78 (P < 0.001).
Conclusions:
Intacs SK could improve visual acuity in patients with moderate and severe keratoconus, yet further studies are needed to draw conclusions about its safety.
