PURPOSE. To compare the results of insertion of low-power posterior
chamber intraocular lenses (PC IOLs) after cataract extraction in eyes with
glaucoma and high myopia with leaving the eye aphakic combined with
trabeculectomy.
METHODS. The outcome of extracapsular cataract extraction (ECCE) with
low-power PC IOLs in 20 consecutive highly myopic and glaucoma (axial length -
25,5 mm or longer) eyes was compared with 21 consecutive highly myopic and
glaucoma eyes receiving ECCE without PC IOLs. Axial length, preoperative visual
acuity, preoperative intraocular pressure, age, sex and follow-up were similar
between both groups.
RESULTS. In the pseudophakic eyes there was a statistically
significantly (p<0,05) better visual outcome, decreased incidence of
posterior capsule opacification and decreased requirement for YAG capsulotomy
(5% versus 10%) Useful visual acuity (>0,1) was achieved in 60% of cases, in
the aphakic eyes - in 42,9%. The mean postoperative spherical equivalent was in
the pseudophakic eyes -1,2 D, in the aphakic eyes - +2,8D. In both groups postoperative intraocular pressure was
compensated. In the aphakic eyes there was sight-threatening one case
suprachoroidal detachment!
CONCLUSIONS. The use of PC IOLs may result in a lower complication rate
and better visual outcome after combined cataract extraction and trabeculectomy
in eyes with glaucoma and high myopia.
