Because all power calculation formulae have been derived from studies done on the adult eye, it is yet unclear which of these would give the best prediction of postoperative refractive error, especially with short axial length (AL) and high keratometry (K) values and a target refraction that ...
and intraocular lens power was calculated with the SRK/T formula.At 1 month after surgery,AL was measured by IOL Master again.The AL measurements by IOL Master(before and after surgery) and contact A-scan were compared,and the refractive outcomes were followed up.Results AL measured by ...
However, consideration of older adults’ quality of life (QoL) has become increasingly important nowadays as there are longer life expectancies and an aging population [8]. Therefore, better understanding of the trends associated with age-related axial length changes may help reduce the burden of ...
The axial length elongation and refraction (spherical equivalent) between the two eyes were observed and compared.A total of 8 myopic patients were enrolled in the study. The AL increased from 24.52±0.96mm to 24.68±1.03mm but without significance (T=1.49, P >0.05) in the ablated eyes. ...
During intraocular lens power calculation, if globe axial length is measured by the contact technique, it will result in the use of an average 1-D stronger IOL power than is actually required. This can lead to induced myopia in the postoperative refraction. In our studied patients, there was...
Each axial length of a silicone oil injected eye was measured on the best CT slice among eyeball cuts, which showed both the insertions of the medial and lateral rectus muscle, the thickest slice of the lens, and the optic nerve. The IOL power for the eyes was determined using the SRK/...
Intraocular lens power calculation in eyes with short axial length AIM: To evaluate and compare the predictive capacity of four intraocular lens (IOL) power calculation formulas (SRK/T, Hoffer Q, Holladay 1, and Haigis) in... MM Moschos,IP Chatziralli,C Koutsandrea - 《Indian Journal of Oph...
Purpose: To assess associations between axial length and density of retinal pigment epithelium (RPE) cells in various ocular regions. Methods: The histomorphometric investigation included histological sections of enucleated eyes of Caucasian patients. Using a light microscope, we counted the number of RP...
their right eye was −2.31 ± 1.06 diopters. There was a significant difference of +8.1 microns which increased the axial length from baseline when reading the usual prescription levels during the first 40 min period. When subjects read in the same situation with the defocus spectacles, the ...
