Abstract
Purpose: :
To evaluate lens densitometry in patients with transparent lens and patients before and after cataract surgery.
Methods: :
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.
Results: :
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.
Conclusions: :
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.
