Clinical Effect Study Of Icl Implantation And Refractive Corneal Laser Surgery In The Same Patient

Study the effectiveness, safety and stability of one eye of the same patient undergoing ICL implantation and the other eye undergoing refractive corneal laser surgery

Refractive surgery department, Chengdu Aier Eye Hospital, China

A total of 28 patients (56 eyes) who underwent ICL implantation in one eye and corneal laser surgery in the other eye at Chengdu Aier Eye Hospital. They were divided into the ICL group and the corneal laser group. In the ICL group, the spherical lens was -4.0D to -14.25D, and the cylindrical lens was ≤ -5.0D; in the corneal laser group, the spherical lens was -1.0D to -6.75D, and the cylindrical lens was ≤ -2.5D. The ICL group underwent ICL or TICL implantation, and the corneal laser group underwent Smile or FS-Lasik surgery. The visual acuity, diopter, visual quality (higher-order aberration), and intraocular pressure, vault, and corneal endothelial cell density after ICL in the two groups were observed. The follow-up time was 2 years.

There was a statistical difference in the BCVA between the two groups before the operation. However, there was no statistical difference in the visual acuity between the two groups at 3 months, 6 months, 1 year and 2 years after the operation. During all the follow-up periods, in the ICL group, the UCVA improved by 1 line in 21 eyes or more in 6 eyes compared with the preoperative BCVA. In the corneal laser group, the UCVA improved by 1 line in 18 eyes or more in 6 eyes compared with the preoperative BCVA. There was no statistical difference in the SE degree and visual quality between the two groups at each time period after surgery. The postoperative refraction of the ICL group was lower than that of the laser group at 2 years.

In the same patient, high myopic eyes undergoing ICL or TICL implantation can achieve the same postoperative effect as low to moderate myopic eyes in the other eye undergoing corneal laser surgery, and the diopter is more stable. The intraocular pressure and corneal endothelial cell density were normal after ICL surgery, with an ideal vault. ICL implantation has high effectiveness, safety and stability.
