Abstract

BARBOSA, Annamaria Ciminelli; QUEIROZ, Renato Sztern; MOTTA, Mario Martins dos Santos  and  PORTES, Arlindo José Freire. Pseudophakic Vision with residual ametropia after pilocarpine 2% instillation. Rev. bras.oftalmol. [online]. 2018, vol.77, n.6, pp.349-352. ISSN 0034-7280.  http://dx.doi.org/10.5935/0034-7280.20180076.

Objective:

Evaluate the visual acuity, refraction, visual field changes and pupillary diameter in pseudophakic patients after instillation of 2% pilocarpine eye drops.

Methods:

Controlled, masked and randomized clinical trial carried out between May, 2015 and September, 2016 at the Gaffrée and Guinle University Hospital, RJ, Brazil. Forty patients, divided into 2 groups, were followed up in the postoperative period of a facectomy with intraocular lens implant. The patients in the group of cases were submitted to a drop of 2% pilocarpine and those of the control group to a drop of lubricant in the operated eye. Before eye drop instillation nd one hour after it, the authors evaluated: visual acuity for distance and near; refraction; pupillary diameter and visual field.

Results:

In case group visual acuity increased from 0.33 to 0.57 for far (p = 0.0001)and also increased for near, 13 patients (59.09%) had visual acuity of J1 or J2 before instillation and 18 or 81.81% after it (p = 0.0054). The median pupillary diameters raised from 2.00 mms to 1.85 mm(p <0.0001). Central visual fields did not have significant alteration. In the control group, there were no statistically or clinically significant changes in any of the measured parameters.

Conclusion:

Topical administration of a 2% pilocarpine eye drop was effective to improve pseudophakic patients vision with residual ametropia for far and near. Additional dose-effectiveness studies may indicate better concentrations and dosages to achieve greater improvements in visual acuity.
