Influence of Biometric and Corneal Tomographic Parameters on Normative Corneal Aberrations Measured by Root Mean Square.

: To determine the impact of corneal and biometry parameters on the normative root mean square (RMS) values of corneal aberrations measured at a 6 mm diameter. : The RMS values for corneal aberrations (anterior, posterior, and total) were measured along with corneal parameters using Scheimpflug tomography on 770 normal subjects. The biometric parameters were measured with an optical biometer.

The Clinical Usefulness of Evaluating the Lens and Intraocular Lenses Using Optical Coherence Tomography: An Updated Literature Review.

The Lens Dysfunction Syndrome includes two widespread ocular disorders: presbyopia and cataract. Understanding its etiology, onset, progression, impact, prevention, and treatment remains a significant scientific challenge. The lens is a fundamental structure of the ocular dioptric system that allows for focus adjustment or accommodation to view objects at different distances.

Suggestion of serious incidents in medical devices used in anterior segment surgery. Proposing ideas (II).

The entry into force of the regulation on medical devices obliges ophthalmologists to identify and report possible serious incidents arising from their use. Faced with the doubts that may arise about what can or cannot be considered a serious incident, a working group of members of the Spanish Society of Refractive and Implant Eye Surgery (SECOIR) and the ophthalmology and vision sciences cluster (Cluster4Eye), have prepared a consensus document that aims to guide ophthalmologists on some of the incidents that, in the experience of the work team, are not common or can cause serious damage to the patient's function in relation to the use of medical devices. Incidents related to the use of viscoelastics, anterior capsule dyes, intraocular lenses, and other items used in anterior segment surgery have been addressed.

Severe epithelial ingrowth after pars plana vitrectomy ten years after LASIK relifting.

Epithelial ingrowth is one of the most significant complications of Laser in Situ Keratomileusis (LASIK) refractive surgery. We present the case of a 72-year-old male with a history of myopic LASIK (1999), who underwent cataract surgery and a second thin LASIK sub-Bowman flap to correct refractive error. Then, three months after pars plana vitrectomy for an epiretinal membrane, the patient complained of progressive vision loss.
