BACKGROUND

To compare the accuracy on intraocular lens power calculation in patients with primary open angle glaucoma (POAG) undergoing isolated cataract surgery or cataract combined with glaucoma surgery, either Express mini shunt device implant (Phaco-Express) or non-penetrating deep sclerectomy (Phaco-NPDS).

METHODS

Sixteen patients who underwent combined Phaco-Express surgery, 22 that received combined Phaco-NPDS and 27 isolated cataract surgeries were analyzed retrospectively. The main objective was to compare the differences between the predicted preoperative refractive aim, with the results of postoperative refraction. Also, number of hypotensive treatment, intraocular pressure decrease and visual acuity improvement were studied.

RESULTS

There were no statistically differences neither in the mean error (ME, difference between postoperative and predicted spherical equivalent) between the 3 groups nor in the mean absolute error (MAE, absolute value of ME), being those measures near to emmetropia in every group. It´s also remarkable that the induced corneal astigmatism (SIA) do not differ in the 3 groups.

CONCLUSION

Combined NPDS or Express mini shunt device and cataract surgery result, in our group, in similar refractive accuracy than cataract surgery isolated, really near to predicted preoperative refractive target. The relevance of these findings is that we can offer an optimal postoperative refractive outcome also in combined glaucoma surgery.
