Article Abstract
Retinitis pigmentosa (RP) and age-related macular degeneration (AMD) are two predominant causes of visual deterioration. Retinal prosthesis embeds a micro-electric chip or a micro-photoelectric diode array in the sub-retina or epi-retina, which is used to stimulate the remainder of inner retina, so as to restore some degree of sight. Retinal prosthesis has attracted most attention in the field of artificial visual function recovery, and along with deep-going research, many issues need to be resolved. In this paper, the theory of retinal prosthesis and the status quo of research in many countries are introduced, the key issues which influence the application of the retinal prosthesis are discussed in detail, and some notions and advices are presented.

Clinical trials of the photovoltaic subretinal prosthesis PRIMA demonstrated feasibility of prosthetic central vision with resolution matching its 100 μm pixel width. To improve prosthetic acuity further, pixel size should be decreased. However, there are multiple challenges, one of which is related to accommodating a compact shunt resistor within each pixel that discharges the electrodes between stimulation pulses and helps increase the contrast of the electric field pattern.

Background: Accurate acetabular cup orientation in total hip arthroplasty (THA) is crucial for successful outcomes. Intraoperative fluoroscopy may be used to evaluate acetabular cup placement. This study aimed to evaluate the accuracy of purely visual estimation of cup inclination and anteversion using intraoperative fluoroscopy, considering different surgeon experience levels and cup designs.

Purpose: To present a case of synthetic intrastromal corneal ring segment (ICRS) intrusion secondary to necrosis and migration, managed by implantation of corneal allogenic intrastromal ring segments (CAIRS) within the preexisting tunnel.
Methods: A 24-year-old man with known keratoconus underwent bilateral ICRS implantation. He presented with blurred vision in the right eye 6 weeks after the procedure.

Purpose: To evaluate tilt, decentration, and axial stability of the Clareon toric intraocular lens (TIOL) (CNW0T3-9; Alcon Laboratories, Inc) over a 6-month follow-up period.
Methods: A single-center, prospective, interventional clinical trial was conducted with a study population of 130 eyes from 82 patients who received a Clareon TIOL. Tilt, decentration, and the aqueous depth were determined preoperatively and at 1 week and 6 months postoperatively using anterior segment optical coherence tomography (Casia 2; Tomey Corporation).
Purpose: To evaluate visual and refractive outcomes, visual quality, patient satisfaction, and spectacle independence 3 months after phacoemulsification with bilateral non-diffractive enhanced depth of focus (EDOF) lens implantation.
Methods: This study included 68 eyes of 34 consecutive patients, with 51.5% undergoing refractive lens exchange and 48.
