Corneal densitometry changes after femtosecond laser-assisted intracorneal ring segments implantation in keratoconus.

Background: Intrastromal corneal ring segments are commonly implanted in the corneas of eyes with mild-to-moderate keratoconus; however, changes in corneal densitometry (CD) after implantation are a matter of debate in the current literature. We evaluated the changes in CD 1 and 3 months after femtosecond laser-assisted Keraring implantation.

Methods: This retrospective, non-comparative, multicenter, case series study included patients with keratoconus who underwent femtosecond laser-assisted implantation of double segments with 90° and 160° arc lengths or two 160° arc length Keraring segments.

Reflections of psychomotor skill development in preclinical simulation: A qualitative analysis.

Introduction: Reflection on competency helps students become more proficient in performing skills, with the ultimate goal of better retention of knowledge and skill. Competency progression involves a complex interplay of factors, and not having the insight of such multiple perspectives of the same experience, we will not be able to understand students as learners fully and consequently may rely on assumption and may not be able to provide the necessary interventions for growth and progress towards competency. This study aims to investigate students' insight of their own progression during psychomotor skill development.
