To evaluate lens densitometry in patients with transparent lens and patients before and after cataract surgery.
We examined a series of 138 eyes of 69 patients, aged from 18 to 76 years. Patients were divided into following groups: group I - 48 eyes of 24 patients with transparent lens (control); group II - 30 eyes of 15 patients with mild cataract; group III - 28 eyes of 14 patients with premature cataract; and group IV - 32 eyes of 16 patients after cataract surgery with different types of intraocular lens. Lens densitometry was measured using non-contact rotating Scheimpflug camera "Pentacam" (Oculus). Results of groups II, II, and IV were compared to group I, using "Microsoft Excel" and "Statistica" software.
Lens densitometry measured by "Pentacam" was 12.6±2.2 standard units in group I, 19.4±4.5 in group II (p<0.01), 28.5±6.5 in group III (p<0.01), and 6.2±2.3 in group IV (p<0.01). All measurements showed high correlation between lens transparency and lens densitometry.
We revealed high positive correlation between lens transparency (natural or artificial lens) and lens densitometry. No correlation was found between lens transparency and lens densitometry between patients of different age groups.
