Optic coherent tomography (OCT) was used to examine 14 persons (15 eyes) before and the following day after laser cataract extraction with intraocular lens implantation. There were slight, but statistically significant differences in the quantitative indicators of OCT in the eyes of immature cataract and pseudophakia (a reduction in the minimum retinal thickness in the foveolar area and that in the design volume of the macular area by the order of 1.4% of the baseline value). The above differences are likely to be largely due to the optic features of the pseudophakic eye; however, this suggestion needs further experimental and clinical studies.
