To measure macular thickness with the Optical Coherence Tomography after Nd-YAG laser posterior capsulotomy in 30 eyes who had undergone previous cataract surgery.
Ophthalmology department, Hospital Avicenne, Bobigny, France. Thirty eyes of 30 patients were included in this prospective single-centre study. Consecutive Nd-YAG laser posterior capsulotomies were performed between january and november 2008. All patients received the same drug protocol after Nd-YAG capsulotomy (acetazolamide, aproclonidine, rimexolone). All patients had a slit-lamp biomicroscopic examination at each visit. Demographic parameters (age, sex and medical history), visual acuity, intraocular pressure, macular thickness, and complications following Nd-YAG laser capsulotomy were analysed. Parameters were studied before Nd-YAG laser capsulotomy, at one week post-capsulotomy, at one month and at 3 months post capsulotomy. The primary outcome measurement was central foveal thickness measured by OCT (Stratus OCT 3, Zeiss). The number of pulses, energy delivered and the interval between cataract surgery and capsulotomy were noted for each patient. A student test was used for statistic data.
The mean age of patient was 72,2+/-11,9 years. The mean visual acuity before laser was 0,6+/-0,3 LogMar. The mean visual acuity were 0,2+/-0,3 , 0,1+/-0,3, 0,1+/-0,3 LogMar at one week, one month, 3 months after Nd-YAG capsulotomy, respectively. The mean macular thickness of the central area were 203,9+/-21,6 µm before Nd-YAG laser and 210,3+/-20,2, 202,1+/-18,9, 207,1+/-15,3 µm at one week, one month and three months after capsulotomy, respectively. There was no statistically increase of macular thickness at each time (p>0,05). There were no complications in our study after Nd-YAG capsulotomy, and no correlation between number of pulses, energy delivered, interval between cataract surgery and macular thickness.
Macular cystoid edema is a classic complication after Nd-YAG capsulotomy. However, there was no significant increase of macular thickness in short-term after Nd-YAG capsulotomy in our study.
