Summary and Conclusion
Neodymium-doped yttrium aluminum garnet (Nd:YAG) laser capsulotomy, which was first described in 1980, is an effective technique and so-called gold standard to treat visually significant posterior capsular opacification (PCO) in pseudophakic eyes ( Oztas,2014).
Posterior capsular opacification is the most common long term complication of cataract surgery .
Nd;YAG capsulotomy can have some changes in anterior chamber depth and refraction
Our study included 19 eyes (4 eyes of male patients and 15 eyes of female patients) who underwent cataract surgery and IOL implantation and were complicated by posterior capsular opacification. All patients received Nd;YAG laser by Zeiss VisuLAS YAG III device with a minimal duration of one year post cataract surgery.
In each visit ACD, Spherical equivalent and IOP before the procedure ,then after one week , one month and 3 months were measured
There was increase in ACD in 8 eyes (42.10%) while 11 eyes (57.90%) showed decrease in ACD .The change in ACD shows significant changes (P = 0.012 , 0.003 respectively).
However, there were no statistically significant changes regarding spherical equivalent in either groups with increased or decreased ACD (P = 0.307 , 1.0 ).
In addition, the intraocular pressure showed no statistically significant change along the follow up periods.
Summary and conclusion
٧٥
We believe that we have some limitations in our study because of the small number of the studied group and the short duration of the follow up periods ,so we recommend to follow up larger number of patients with different types of IOLs and for longer duration. |
