Abstract Details

Purpose:

To evaluate the results of allograft corneal inlay (ACI) implantation in a case series of 28 hyperopic eyes of 16 patients.

Setting:

Istanbul Medipol University, Faculty of Medicine, Ophthalmology Department, Istanbul, Turkey

Methods:

Cases with manifest refraction spherical equivalent (MRSE) between 1.00 - 6.00 D and having a cylindrical refraction of less than 1 D were included in this prospective study. The refractive power of the excimer laser shaped ACI (Transform, Allotex Inc. Boston, USA) were selected according to the refractive error of the subject’s eye. All ACI were centered with respect to the center of the pupil after the creation of a femtosecond flap (flap thickness 110 microns). Visual acuities, refractive results and intra- and postoperative events were evaluated within the first 12 months follow-up period.

Results:

The mean age of the patients included in the study was 36.2±12.4 (range 22-65) years. Of the 28 eyes operated, 15 were right and 13 left eyes. The mean preoperative MSRE of 3.6±1.51 was decreased to 0.21±0.56 (p=0.000). The uncorrected distance and near visual acuity increased from 0.33±0.22 and 0.17±0.13 to 0.75±0.22 (p=0.000), 0.72±0.19 (p=0.000) respectively. The best corrected distance visual acuity remained unchanged (pre-OP: 0.79±0.22; post-OP: 0.80±0.21; p=0.916) and best corrected near visual acuity increased from 0.78±0.22 to 0.84±0.20 (p=0.003). Mean K-value, central corneal thickness increased from 42.57±0.81 and 557.5±43.0 to 44.8±1.4 (p=0.000), 597.1±58.1 (p=0.000), respectively. There were no clinic relevant postoperative complications such as diffuse lamellar keratitis, epithelium ingrowth or decentralization.

Conclusions:

Excimer laser shaped allograft corneal inlays offers an alternative treatment modality in patients with hyperopia. Regression is often seen in the long term in refractive laser treatment of higher hyperopic patients were found to be lower compared to other corneal refractive procedures.
