Abstract Details


To explore the safe and effective method of reducing the viscoelastic retaining during the implantation of implantable collamer lens to avoid elevated intraocular pressure (IOP)in the early postoperative period due to retained viscoelastic.


Residues of viscoelastic agents in ICL often cause postoperative complications of high intraocular pressure in the early postoperative period. It is often necessary to remove residual viscoelastics from the anterior chamber or the anterior chamber after surgery, which poses a safety hazard to the operation.


A retrospective study included 486 eyes of 246 patients underwent implantation of implantable collamer lens. The eyes were devided into two groups: Group A, conventional group, Group B, modified group. IOP over 21mmHg at 2hs, 4hrs,6hrs postoperatively were considered as elevated. The residual of viscoelastic was estimated after surgery under slit lamp and compared between the two groups. IOP at 2hs, 4hrs,6hrs postoperatively and the incidence of elevated IOP were evaluated and then compared.


The residual of viscoelastic in Group A is more than in Group B. IOP in Group B is significantly lower 2hrs and 4hrs after surgery (P =0.000). The incidence of elevated IOP was 22.64% (48/212) in Group A, significantly higher than 4.74% (13/274) in Group B (P =0.000). 3 eyes of elevated IOP in Group A developed anterior subcapsular opacity 1 year postoperatively whereas no eye in Group B.


The modified method can effectively reduce the incidence of elevated IOP in the early postoperative period due to retained viscoelastic.
