Refractive and topographic fluctuations due to intracorneal ring segments motility

Summary
Intracorneal ring segments (ICRS) can migrate after corneal ectasia treatment, causing vision loss. Surgical repositioning and fixation can restore visual function and prevent segment override.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Refractive Surgery
Background:
- Intracorneal ring segments (ICRS) are used to manage corneal ectasia post-LASIK.
- Long-term complications of ICRS implantation require investigation.
Observation:
- A patient experienced fluctuating vision 5 years after ICRS implantation.
- Slit-lamp and OCT revealed ICRS overriding, which temporarily resolved with corneal massage.
Findings:
- ICRS override significantly impacted refractive and topographic measurements, leading to decreased visual function.
- Surgical repositioning and fixation with a suture successfully stabilized the ICRS and resolved the issue.
Implications:
- ICRS migration and override are potential complications of femtosecond laser-assisted ICRS implantation.
- Surgical intervention for repositioning and fixation can effectively manage ICRS complications, improving visual outcomes.

01:16Focusing of Light in the Eye
6.2K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

1.7K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...
