Abstract Details

Purpose:

To evaluate the safety, effectiveness and predictability of allogeneic corneal len inlays to correct hyperopia.

Setting:

Ophthalmic Center, Beijing Tongren Hospital, Capital Medical University, Beijing Ophthalmology & Visual Sciences Key Lab, Beijing, China.

Methods:

It was a prospective case-control study. Twenty-one hyperopic patients (37 eyes) were performed with allogeneic corneal len inlays. The range of preoperative spherical equivalent was +3.25～+10D, and its mean value , （+6.84±2.79）D. All the cases were followed up for 3 months. Uncorrected and best corrected visual acuity and refraction were compared between before and after operation. Corneal topography and optical coherence topography were examined to reflect corneal topogeaphy. Ocular response analyzer was used to evaluate the shifts of corneal hysteresis.

Results:

No intraoperative and postoperative complications were found. Uncorrected distance (UCDVA) and near visual acuity (UCNVA) improved obviously after surgery. UCDVA improved obviously from （4.64±0.25）to（4.89±0.14）and UCNVA improved obviously from J4.94 to J1.18. Mild overcorrection was the state early after operation, and the diopter was stable about 1 month after surgery. The average residual spherical equivalent was （-0.63±0.94）D, which improved obviously from （+6.84±2.79）D before surgery. There was no obvious hyperopic fallback phenomenon. The corneal biomechanics didn't change before and after surgery.

Conclusions:

Allogeneic corneal len inlays can be used to correct hyperopic eye with good safety, effectiveness and predictability. It provides a new choice for hyperopic patients.
