Abstract Details

Purpose:

To compare the visual, refractive and biomechanics parameters outcomes between femtosecond laser microincision corneal matrix lens (SMILE 3.0) and intraocular lens implantation (ICL) for the treatment of myopia.

Setting:

The XI’AN AIER eye hospital, The AIER eye institute of Central south university, Changsha，Hunan Province, China

Methods:

One-year, non-randomized, prospective study of 25 myopic eyes of 25 subjects using ICL for one eye and SMILE for the fellow eye. Visual acuity, refraction, low-order aberration (LOA), High-order aberration (HOA), the corneal stiffness parameter at the first applanation (SP-A1) and biomechanically corrected intraocular pressure (bIOP) were compared before and after treatment.

Results:

The visual acuity (UCVA) was improved by one or more rows both in the ICL and SMILE groups. There was no significant difference between the proportion of UCVA reaching 20/20 or above(P=0.65), spherical equivalent (P=0.88), vertical weight difference(P=0.75) and horizontal weight difference(P=0.08). Post-corneal aberration of the two groups was not statistically significant (P>0.05) after surgery, and the differences of coma, spherical aberration and total high-order aberration between the two groups were not significantly (P>0.05). Compared with the SMILE group, the SP-A1 and bIOP value were not altered significantly in the ICL group(P>0.05).

Conclusions:

At 1-year, both SMILE3.0 and ICL produces excellent UCVA, improves BSCVA, and reduces visual symptoms with a high level of patient satisfaction, while the precorneal high-order aberration and corneal stiffness after ICL superior to SMILE.
