Abstract Details
Purpose:
To compare the optical biometry results provided by "IOLMaster 500", "IOLMaster 700", "Lenstar LS 900" and "Revo Soct Copernicus" before and after scleral buckling procedure in eyes with retinal detachment.
Setting:
"Medical Military Academy named after S.M. Kirov”of the Ministry of Defense of the Russia
Methods:
The study includes results of optical biometry and keratometry of 20 patients (20 eyes) with retinal detachment complicated by proliferative vitreoretinopathy of stages B and C. All patients underwent measurement with “IOLMaster 500”, “IOLMaster 700”, “Lenstar LS 900” and “Revo Soct Copernicus” before and after surgery. The average age of the patients was 49.33±19.14 years (from 23 to 68 years).
Results:
After scleral buckling procedure according to all biometry data AL significantly increased (0.65±0.21 mm, 0.71±0.23 mm, 0.69±0.22 mm and 0.55±0.38 mm respectively, p<0,05) and ACD values decreased reliably (0.49±0.31 mm, 0.57±0.37 mm and 0.32±0.21 mm, p<0,05) only for “IOLMasters 500”, “IOLMasters 700” and “Revo Soct Copernicus”. The lens thickness significantly increased (0.22±0.17 and 0,23±0.21 mm, p<0,05) according to “Lenstar LS 900” and “Revo Soct Copernicus”. The WTW decreased by 0.49±0.68 mm according to “Lenstar LS 900” (p=0,043). Keratometry data doesn’t have significant shift, whereas corneal astigmatism significantly increased by 1.06±0.82 D (p=0,027) according to the “IOLMaster 500”
Conclusions:
According to data of various types of optical biometry after episcleral buckling procedure significant increase was determined not only in the AL data, but also in the crystalline lens thickness accompanied by an anterior chamber depth shallower.
Despite absence of significant deviation in keratometry data a reliable induction of corneal astigmatism as a result of extrascleral surgery was revealed.
