To evaluate the effects of the encircring scleral buckling on the variations in refractions of the cornea.
Twelve eyes of 11 patients, who underwent encircring scleral buckling surgeries to treat rhegmatogenous retinal detachment at Tokyo Medical University Hospital from November 2006 to July 2007, were included in this study. Spherical equivalent was measured with auto-refract meter before surgery and 1 week, 1 month and 3 months after surgery. Depth of anterior chamber, average corneal curvature was also analyzed with PENTACAM® before surgery and 1 week, 1 month and 3 months after surgery. To evaluate aberrations, the zero-order component, the third order and the forth order in the Zernike polynomials of front and back of the cornea was measured with PENTACAM® before surgery and 1 week, 1 month and 3 months after surgery as well.
Mean spherical equivalent was -5.08D, -7.11D, -7.06D and -7.13D before surgery and 1 week, 1 month and 3 month after surgery, respectively. Statistical difference was detected between before and each time point of after surgery. Mean depth of anterior chamber was 3.414mm, 3.179 mm, 3.096 mm and 3.457mm, respectively. Average corneal curvature of front and back of the cornea were 7.993 and 6.445mm, 7.997 and 6.377mm, 7.889 and 6.430mm and 8.062 and 6.499mm, respectively. Average of the zero-order component of the aberration of front and back of the cornea was 0.0967 and 0.1231µm, 0.0965 and 0.1225µm, 0.0978 and 0.1217µm and 0.0957 and 0.1211µm, respectively. Average of the third order of front and back was 0.00937 and 0.01523, 0.00934 and 0.01503µm , and 0.00957 and 0.0148µm and 0.00919 and 0.0147µm, respectively. Average of the fourth order of front and back was 0.00052 and 0.00092µm, 0.00059 and 0.00103µm, 0.00056 and 0.00099µm and 0.00052 and 0.00134µm , respectively. There was no significant difference in any time point in the depth of the anterior chamber, corneal curvature and aberrations.
Even though spherical equivalent is affected, the encircring scleral buckling does not change the aberrations of the cornea. Supporting the usefulness of encircring scleral buckling accompanied with the existence of the accommodation.
