Abstract
Introduction: Nd: YAG laser capsulotomy is relatively a non-invasive procedure which is used as
a treatment in patients with posterior capsular opacification (long-term complication after cataract
surgery).
This complication is seen more in patient after ECCE technique compared to Phaco technique,
leading to reduced postoperative visual acuity, glare and primary clouding lens symptoms.
Opacification of posterior capsule ”secondary cataract” is caused by increased epithelial cells
proliferation, which leads to fibrous changes and posterior capsule opacification, the frequency
varies from 8.7% to 33.4%.
Design: Retrospective study in a period of 2004-2014 years of 116 eyes
Aim: The aim is to assess the influence of YAG-laser capsulotomy on the intraocular pressure in
patients with secondary clouding of posterior capsule after cataract surgery.
Material and methods: The study included 116 patients with age SD 64 +/- 7 years, who had a
cataract intervention with implantation of an artificial intraocular lens. Due to varying degrees of
the posterior capsule opacification with the consequent decrease in visual acuity , postoperatively
method of Nd: YAG laser capsulotomy or photo disruption was performed. For a period of ten years
(2004 - 2014) analysis have been done on the patients, treated by one doctor, providing a single
protocol and consistency of results. The effect of the intervention on intraocular pressure (IOP)
and the risk factors were analised also. Tonometry on both eyes was performed in each patient
pre treatment within the preparation protocol of the patient, and one hour after the intervention.
Sixteen of the patients were already diagnosed with glaucoma before the intervention.
Results: Changes of the intraocular pressure in the prophylactic treated eyes with topical beta
adrenergic agonist were unremarkable compared to the control group where a significant transient
increasing of the IOP after a time interval was. The increase in IOP was significantly associated
with an interval of 1 hour measurement after the capsulotomy has been performed. Glaucoma
patients are more likely to need a long-term IOP control with additional antiglaucomatous drugs
than the patients without glaucoma pre-intervention.
No correlation was established between the strength of the laser energy and pulse number applied
in relation to the intraocular pressure increas
