Purpose
The purpose of this study was to compare the visual outcomes and corneal densitometry (CD) between allogenic lenticule intrastromal keratoplasty (AL-LIKE) and autologous lenticule intrastromal keratoplasty (AU-LIKE) for the correction of moderate-to-high hyperopia.
Setting
Eye Institute and Department of Ophthalmology, Eye & ENT Hospital, Fudan University
Methods
A total of 10 subjects (14 eyes) underwent AL-LIKE, and eight subjects (8 eyes) underwent AU-LIKE. The subjects were examined preoperatively and at one day, one month, and six months postoperatively. The visual outcomes and CD were evaluated and compared between the two surgical methods.
Results
The efficacy index was 0.85±0.18 and 0.90±0.33 in the AL-LIKE and AU-LIKE groups, respectively. The safety index was 1.07±0.21 in the AL-LIKE group and 1.25±0.37 in the AU-LIKE group. The CD values of the anterior, central and posterior layers in the AL-LIKE group increased significantly one day postoperatively (all P < 0.05). The CD values of the anterior and central layers were still significantly higher than the preoperative values six months postoperatively (all P < 0.05). The CD values of the anterior layer in the AU-LIKE group increased significantly one day postoperatively (all P < 0.05) and decreased to the preoperative values (all P > 0.05) one month postoperatively.
Conclusions
AL-LIKE and AU-LIKE had similar efficacy and safety. However, AU-LIKE had a smaller affected area and faster recovery time related to changes in corneal transparency.
