Purpose:
To evaluate and compare visual outcomes and postoperative complications rate of cataract surgery with the primary IOL implantation in children, who underwent the surgery at the age of less than 4 months, in group with unilateral versus bilateral cataract.
Setting:
Department of Ophthalmology for Children and Adults, 2nd Medical Faculty, Charles University, FN Motol, Prague, Czech Republic.
Supported by CZ.2.16/3.1.00, MZO FNM 2005
Methods:
The study was designed as retrospective, nonrandomized, single center. The inclusion criteria were: congenital cataract surgery with primary IOL implantation at the age of less than 4 months during the years 2005-2010, follow up at least 12 months, valid visual acuity measurement either by preferential looking method or Snellen charts. Following parameters were evaluated: the best corrected visual acuity (BCVA) obtained during the last follow-up, compliance with contact lenses and glasses wearing and three main postoperative complications (posterior capsule opacification - PCO, secondary glaucoma and cyclitic membrane formation). The patients were divided into 2 groups, group A involved patients with unilateral congenital cataract, group B involved patients with bilateral disease.
Results:
The inclusion criteria were reached by 38 patients. Group A was formed by 19 eyes of 19 patients, average age of the surgery 1,86 ± 0,93 weeks, follow up 44,32 ± 23,95 weeks. Group B was formed by 35 eyes of 19 patients, average age of surgery 2,25 ± 0,92 weeks, follow up 26,89 ± 14,12 weeks. The compliance with contact lenses and glasses wearing was high in both groups: 84% in group A and 91% in group B. PCO surgery was indicated in 74% in group A and in 60% in group B. Secondary glaucoma occurred in 10% in group A and in 40% in group B and cyclitic membrane formation was diagnosed in 32% in group A and in 34% in group B. Average BCVA (Snellen charts) was 0,41 ± 0,37 in group A and 0,64 ± 0,36 in group B.
Conclusions:
Our study showed higher rate of secondary glaucoma in the group of bilateral congenital cataract. Other postoperative complications as well as the compliance with contact lenses and glasses wearing were at the similar level in both groups. Better BCVA was followed in the group of bilateral disease. Higher compliance with patching and amblyopia treatment in this group could be an explanation of this result. FINANCIAL DISCLOSURE?: No
