A study by Hocauglu et al19 showed intraoperative complications as: posterior capsular plaque in 9.7% cases, posterior capsule rupture in 5.5% cases, loss of nuclear material into vitreous in 3.3% cases and zonular dialysis in 2.3%19.
Tension and contact between the lens capsule and zonule decrease with weakness of the zonular apparatus, rendering the lens thicker and ever more mobile.
Zonular and lenticular pigmentation were strong evidence for diagnosis of PDS/PG in that they were demonstrating the existence of irido-zonular rubbing, cause of pigment dispersion.
After obtaining the approval from ethical research/review committee, 29 patients having subluxated lenses with zonular weakness less than 180 degrees were recruited to the study for lens aspiration, modified CTR (type 1G Morcher) and posterior chamber IOL implantation.
Bilateral zonular cataract associated with the mitochondrial cytopathy of Pearson syndrome.
Patients unsuitable for this type of IOL include eyes requiring complicated cataract surgery, excessive zonular weakness, chronic uveitis, active rubeosis iridis, and central corneal opacities.
Intraoperative use of a capsule tension ring reduces the risk of zonular rupture but is no guarantee against intraocular lens dislocation in the long term.
Throughout the postoperative course the patient required both anterior chamber and vitreous tap (postinjection days 2 and 4, resp.) to manage elevated intraocular pressure secondary to partial migration of the gas bubble into the anterior chamber, presumably due to zonular dehiscence.
Punctate and flakelike lesions and iridescent crystals appear in the anterior cortex, or, less frequently, a zonular type of cataract may appear.
This result is similar to the finding in the literature.3,15,16 However, explanations for this finding may be due to zonular weakness, type of cataract, anterior displacement of lens iris diaphragm and increased age.
Striate Keratitis on first post-operative day was observed in 2 patients, intraocular lense was displaced in 2 patients and zonular dehiscence occurred in 1 patient after Conventional ECCE procedure with posterior chamber lense.
We thought that this may be due to difficulties in calculating the ELP arising from zonular laxity in (PEX) patients.
