Surgical correction of refractive errors

open access: yes, 2022
Refrakcijske greške oka predstavljaju greške u mogućnosti fokusiranja oka na objekte koje gledamo, koje rezultiraju smanjenom vidnom oštrinom. Refrakcijske greške dijele se na kratkovidnost (myopia), dalekovidnost (hyperopia), astigmatizam (astigmatismus)

Corneal re-innervation following refractive surgery treatments

open access: yesNeural Regeneration Research, 2019
Laser refractive surgery is one of the most performed surgical procedures in the world. Although regarded safe and efficient, it has side effects. All of the laser based refractive surgical procedures invoke corneal nerve injury to some degree.

Visual outcomes after three different surgical procedures for correction of refractive error in patients with thin corneas [PDF]

open access: yesInternational Journal of Ophthalmology, 2020
AIM: To investigate and compare the visual and refractive outcomes of small incision lenticule extraction (SMILE), laser assisted sub-epithelial keratomileusis (LASEK), and LASEK combined with corneal collagen cross-linking (LASEK-CXL) surgery in ...

Toric implantable collamer lens for keratoconus

open access: yesIndian Journal of Ophthalmology, 2013
Keratoconus is a progressive non-inflammatory thinning of the cornea that induces myopia and irregular astigmatism and decreases the quality of vision due to monocular diplopia, halos, or ghost images.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Unraveling the impact of laser refractive surgery on corneal ectasia: an in silico study

open access: yesFrontiers in Bioengineering and Biotechnology
IntroductionLaser refractive surgeries are a safe option for low-to-moderate refractive corrections, providing excellent visual outcomes. Over the years, various procedures have been introduced into clinical practice, but the most performed today remain ...
