Abstract Details

Purpose:

To investigate safety of one-step viscoelastic agent technique for posterior chamber phakic implantable collamer lens with a central hole (ICL V4c) implantation for myopia correction.

Setting:

EENT Hospital of Fudan University

Methods:

One-step viscoelastic agent technique for ICL V4c implantation was developed and used in 100 eyes of 52 patients. Refractive outcomes, intraocular pressure, corneal endothelial cell and corneal densitometry was evaluated 1 day, 1 week, 1 month and 3 months postoperatively.

Results:

All surgeries were uneventful. No CDVA was lost. IOP was 16.21±3.36 mmHg before surgery, and 14.74±3.08, 14.30±2.36 and 14.50±2.56 mmHg at 1 day, 1 m, and 3m after surgery (P<0.05). Corneal endothelial cell density was 2580±242 cell/mm², coefficient of variation in cell size was 42.1±7.9% before surgery, no significant difference was found when comparing between time points (P>0.05). Corneal densitometry values of the central 2 mm and 6 mm area showed similar regularities, which significantly increased at 1 day (P<0.05) and then decreased to the preoperative values at 1 week (P>0.05), and then continued to decrease in 3 months (P<0.05).

Conclusions:

One-step viscoelastic agent technique for ICL V4c implantation exhibited great safety for myopia correction, which is worthy of a longer period and larger population study.
