Intraocular Pressure After Corneal Refractive Surgery [PDF]

Medical Archives, 2018
Laser in situ keratomileusis (LASIK), a refractive surgery procedure is being performed in a large number among people with refractive errors. In all the people undergoing the procedure, there is a potential risk to misdiagnose the glaucoma disease due to changes in central corneal thickness (CCT).

Epithelial ingrowth following laser in situ keratomileusis (LASIK): prevalence, risk factors, management and visual outcomes [PDF]

, 2018
The number of laser in situ keratomileusis (LASIK) procedures is continuing to rise. Since its first application for correcting simple refractive errors over 25 years ago, the role of LASIK has extended to treat other conditions, including ...

Dyskeratosis Congenita and Corneal Refractive Surgery [PDF]

Ophthalmology and Therapy, 2019
Dyskeratosis congenita is a syndrome of bone marrow failure secondary to unstable telomeres. It is characterized by a range of mucocutaneous diseases. Due to premature telomere shortening, these patients have limbal stem cell deficiency leading to poor regeneration and maintenance of the cornea.

Upconversion Nanoparticles Embedded Photonic Contact Lens for Transepithelial Corneal Crosslinking Using Hyaluronate – Riboflavin Conjugate

Advanced Functional Materials, EarlyView.
A minimally invasive, transepithelial corneal cross‐linking (TE‐CXL) approach is presented using upconversion nanoparticles (UCNPs)‐loaded contact lenses (UCLs), after topical delivery of hyaluronate–riboflavin conjugates. The NIR‐to‐UV/blue light conversion by UCNPs in a UCL can activate riboflavin for TE‐CXL, resulting in the biomechanical strength ...

Comparison of intraocular pressure measured by ocular response analyzer and Goldmann applanation tonometer after corneal refractive surgery: a systematic review and meta-analysis

BMC Ophthalmology, 2020
Background Accurate measurement of intraocular pressure (IOP) after corneal refractive surgery is of great significance to clinic, and comparisons among various IOP measuring instruments are not rare, but there is a lack of unified analysis.

Analysis of best corrected visual acuity following corneal refractive surgery comparing low and standard predicted postoperative keratometry [PDF]

, 2018
BACKGROUND: It is a commonly held view in the ophthalmologic community that eyes with sufficiently low calculated postoperative corneal keratometry, less than 35 diopters, should not undergo corrective refractive laser surgery (CRLS) due to the increased

Novel Functional Materials via 3D Printing by Vat Photopolymerization

Advanced Functional Materials, EarlyView.
This Perspective systematically analyzes strategies for incorporating functionalities into 3D‐printed materials via Vat Photopolymerization (VP). It explores the spectrum of achievable functionalities in recently reported novel materials—such as conductive, energy‐storing, biodegradable, stimuli‐responsive, self‐healing, shape‐memory, biomaterials, and

Determination of the Elastic Modulus of Cornea of Myopia Patients Based on Pentacam and Corvis ST

Taiyuan Ligong Daxue xuebao, 2022
The biomechanical properties of the cornea are of great significance to corneal refractive surgery and postoperative corneal deformation, development, and pathology. In this paper, a geometric model of the cornea of myopia was established on the basis of

Keratoprostheses for corneal blindness: a review of contemporary devices [PDF]

, 2015
According to the World Health Organization, globally 4.9 million are blind due to corneal pathology. Corneal transplantation is successful and curative of the blindness for a majority of these cases. However, it is less successful in a number of diseases
