Ocular Biometry Parameters before Cataract Surgery

Aim of the study: To evaluate ocular biometry parameters before cataract surgery. Objectives: 1. To evaluate the change of axial length, anterior chamber depth, keratometry parameters, corneal astigmatism in different age groups. 2. To evaluate axial length, anterior chamber depth, keratometry parameters, corneal astigmatism according to sex. 3. To evaluate types of corneal astigmatism according to age and sex. 4. To evaluate types of corneal astigmatism in different axial length groups. Material and methods: A retrospective study included patients before cataract surgery. Patients were divided according to age: ≤ 60 years (y), 61-70 y, 71-80 y, ≥ 81y. The data about axial length (AL), anterior chamber depth (ACD), keratometry parameters (K1, K2) and corneal astigmatism was obtained from patients‘ records. The data was analyzed by using SPSS package, after selecting the significance level p 1.0 D, was more common in men than in women. No significant difference in the frequency and types of astigmatism was observed in axial length groups. Short ocular axes were more commonly found in women. Practical recommendations: Assessment of preoperative corneal size and types of astigmatism is necessary not only to provide additional information to cataract surgeons before surgery, but also to plan the demand for toric intraocular lenses before surgery, taking into account the effects of population aging
