Abstract Details

Purpose:

To study the efficiency of trabeculocleaning performed in course of Femto-laser assisted cataract surgery (FLACS), with a preliminary suprathreshold SLT.

Setting:

The Volgograd branch of S.Fyodorov Eye Microsurgery Federal State Institution.

Methods:

The study included 26 patients with a complicated cataract and primary open angle glaucoma with concomitant pseudoexfoliation syndrome (25 eyes with the early, 5 eyes with the developed and 1 eye with the advanced stage of disease). The initial IOP values were 23.2 ±0.18 mm Hg, the outflow facility coefficient was 0.12±0.0017 mm3 /mm Hg. All patients underwent a suprathreshold SLT preceding FLACS and hydrodynamic trabeculocleaning, in course of which trabecular debris were removed with the help of aspiration-irrigation tips. A comparative colorimetric analysis of the acquired images with application of graphical query Paint was undertaken in postoperative period.

Results:

One month postoperatively mean IOP value decreased to 14,5±0,14 mm Hg, i.e. by 8,7 mm Hg from initial values (37,5%), the outflow facility coefficient improved to 0,21±0,002 mm3/mm Hg*min (p<0,001). In 24 cases (77%) IOP was compensated without application of antihypertensive drugs, in 7 cases (22,4%) it reduced under medication. Findings of colorimetric analysis revealed an increase of R, G, B indicator values graded from dark to light on a scale from 0 to 255 with values ΔR=60,9%, ΔG=32,7% and ΔB=23,3 %, which points at attenuation of staining degree thus confirming the ACA detersion from trabecular debris.

Conclusions:

Hydrodynamic trabeculocleaning in course of FLACS with preliminary suprathreshold SLT ensures ACA detersion from trabecular debris: pseudoexfoliation material and pigment granules, therefore aiding to preserve and activate natural pathways to the outflow of intraocular fluid.
