the choice of surgical treatment in patients with cataract and asteroid hyalosis.


Sverdlovsk Regional Clinical Hospital №1, Yekaterinburg, Russian Federation


24 patients aged 67 - 83 years with cataract and asteroid hyalosis were divided into 3 groups.  Preoperative group 1 had the best corrected visual acuity (BCVA) from 20/500 to 20/63, the amount of points on the Visual Function Questionnaire-14 was 2-35 (VF-14), phacoemulsification and three-port total pars plana vitrectomy (PPV) was performed. Patients of 2 group who underwent phacoemulsification with subtotal vitrectomy (STV) through posterior capsulorhexis had BCVA from 20/600 to 20/50, score 3-45. In group 3 BCVA was from 20/500 to 20/63, the score 2-39, cataract phacoemulsification was performed.


In group 1 BCVA was from 20/32 to 20/20, VF-14 was from 93 to 100. Patients from group 2 had BCVA from 20/32 to 20/20, VF-14 from 80 to 97. Group 3 had BCVA from 20/40 to 20/25, VF-14 from 76 to 94. In one case of group 1 the macular profile was found to be uneven due to the removal of the posterior hyaloid membrane (PHM) fixed in the macular zone. In one case from group 1 after 4 months we diagnosed an epiretinal membrane with thickening of the macular interface and decreased BCVA from 20/25 to 20/50.


Performing STV through posterior capsulorhexis is preferable if PHM is fully fit or detached. Realization of STV through the posterior capsulorexis retains the intact PHM, eliminates the traction component on the fixation points. Minor remains of asteroid hyalosis may cause patient dissatisfaction. If incomplete detachment of the PHM with fixation in the central zone, then preferable to perform a PPV with the removal of PHM. In the absence of sufficient preoperative information, subtotal vitrectomy is preferable as a less traumatic method.
