Abstract

Role of Anterior Segment OCT in Precising Biometry of White Cataract

Hesham M. El Mazar, Sara Abdel Meged Nage Attia* and Ahmed Esmael Mohammed Ramadan

Aim: To correlate between Anterior Segment Optical Coherence Tomography (AS-OCT) and ultrasonography to achieve precise Intraocular Lens (IOL) power of white cataract.

Materials and methods: A prospective non randomized study was conducted at a special eye center at Menoufia from October 2019 to February 2020. This study was conducted on 60 eyes of 60 patients with white cataract who were going to have elective unilateral standard phacoemulsification and IOL implantation. AS-OCT was performed preoperatively in all diseased individuals (n=30) which were categorized into 2 groups. Group 1 with presence of sub-capsular fluid pockets and those without any fluid are Group 2. Pre and postoperative data of both groups was recorded and compared.

Results: IOL power ranging from (20.0 D-24.0 D) with Mean ± SD. (22.0 ± 1.18) in cases with sub-capsular fluid pocket. In cases with no sub-capsular fluid pocket, IOL power ranging from (21.0 D-25.0 D) with Mean ± SD (23.37 ± 1.46). There was clinical significance between IOL power and sub-capsular fluid pocket (P=0.013). Post-operative follow up after one month show that refraction in cases with sub-capsular fluid pocket is hypermetropic more than 1 dioptre with Mean ± SD (1.27 ± 0.24). While refraction in all the diseased individuals without sub-capsular fluid pocket is nearly emmetropic with slight intended myopic shift with Mean ± SD (-0.93 ± 0.29).

Conclusion: Biometry for white cataract with sub-capsular fluid needs further research to get suitable formula.
