The properties of the biomaterials used to constitute lenses are important factors choosing a lens for human implantation because these can influence in posterior clinical evolutions of patients. In this study, different characteristics of intraocular lenses such as chemical composition, surface roughness and lens design have been investigated in terms of their influence into a pathological environment. Eight commercial lenses were tested by optical profiling, Infrared spectra with Fourier transformation (FTIR), water-material contact angle and scanning electron microscope (SEM) to know their chemical composition and structural characteristics. These lenses were then exposed to infectious conditions in order to evaluate their responses to the bacterial environment.

To analyze the refractive accuracy of a novel swept-source optical coherence biometer (SS-OCT), that uses individual refractive indices to measure axial length, in short and long eyes implanted with monofocal intraocular lenses (IOLs). This retrospective comparative study considered eyes with short axial length (AL) (< 22.5 mm) or long AL (> 26 mm) bilaterally implanted with the Acrysof IQ monofocal IOL.

A 65-year-old male patient presented to eye outpatient department of a zonal hospital in North Eastern India with complaints of diminution of vision for 1-year duration. On ocular examination, his unaided visual acuity was 6/36 right eye and 6/12 left eye. He was diagnosed as a case of immature senile cataract with nuclear sclerosis grade 2+ in the right eye and immature senile cataract with nuclear sclerosis grade 1+ in the left eye, with no other ocular or systemic findings.

Purpose: To evaluate visual outcomes and quality of vision following bilateral implantation of a hydrophobic acrylic intraocular lens (IOL) in eyes targeted for emmetropia.
Methods: This was a prospective, single arm study. Subjects were bilaterally implanted with the Clareon PanOptix IOL and evaluated at 1 and 3 months postoperatively.

To develop and validate a predictive model for assessing the risk of early postoperative high intraocular pressure (HIOP) following posterior chamber intraocular lens implantation. The clinical data of patients who underwent posterior chamber intraocular lens implantation at the Second Affiliated Hospital of Zhejiang University School of Medicine between May 2023 and April 2024 were retrospectively reviewed. Patients were divided into a modeling group and a validation group with a 7∶3 ratio using computerized random allocation.
