Abstract Details

Purpose:

To compare post-operative intraocular pressure (IOP) after intraocular lens (IOL) implantation using hydroxypropylmethylcellulose 2% (HPCM 2%) and hydro-implantation after 24h and a week after refractive lens exchange surgery.

Setting:

Clínica Baviera, Málaga, Spain

Methods:

This retrospective study included 78 eyes of 39 patients who had refractive lens exchange. We divided them in two groups: (1) 38 eyes had IOL implantation with HPMC 2% and (2) 40 eyes had IOL hydro-implantation. Post-operative IOP changes were compared with the preoperative IOP of the same group, and between the two groups at 24h and weekly control.

Results:

Mean patients age was 55.2 years (SD 6.6), similar in both groups (p-value =0.06). There was no significant difference in mean preoperative IOP (group 1 =16 mmHg, SD 3.2, group 2 = 16.1, SD 2.7, p-value =0.87). The day after the surgery both groups had statistically significant elevation in IOP (p-value=0.01), but without differences between them (IOP in group 1 =18 mmHg and in group 2=18.3 mmHg, p-value=0.73), and returned to preoperative values one week after surgery.

Conclusions:

In our study, the use of hydro-implantation to insert the IOL in refractive lens exchange, compared with the use of HPMC 2%, resulted no advantage to prevent IOP elevation postoperatively.
