Summary
Cataract surgery (phacoemulsification) can affect choroidal thickness. Subfoveal choroidal thickness (SFCT) significantly increased three months post-surgery, correlating with intraocular pressure changes.
Area of Science:
- Ophthalmology
- Retinal Imaging
- Choroidal Physiology
Background:
- Phacoemulsification, a common cataract surgery, induces ocular inflammation affecting both retina and choroid.
- Understanding the impact of cataract surgery on choroidal thickness is crucial for patient outcomes.
Purpose of the Study:
- To evaluate subfoveal choroidal thickness (SFCT) changes after uneventful phacoemulsification using swept-source optical coherence tomography (SS-OCT).
Main Methods:
- Prospective study of 30 eyes undergoing uncomplicated phacoemulsification and intraocular lens implantation.
- Measurements of SFCT and foveal retinal thickness (FRT) using SS-OCT at baseline, 1 month, and 3 months postoperatively.
- Analysis of SFCT changes correlated with axial length, age, and intraocular pressure (IOP) variations.
Main Results:
- A statistically significant increase in mean SFCT was observed at 3 months post-surgery across most sectors.
- SFCT changes correlated with patient age and baseline IOP.
- Mean foveal retinal thickness (FRT) also showed a significant increase post-surgery.
Conclusions:
- A subclinical increase in SFCT was noted at 1 month, with a significant increment by 3 months post-cataract surgery.
- The observed SFCT increase was correlated with surgery-induced changes in IOP and ocular perfusion pressure.

339
Effective lubrication between a rotating shaft and its bearing housing is essential in rotating machinery to minimize friction, wear, and energy loss. With carefully controlled thickness and viscosity, the lubricant layer prevents metal-to-metal contact, ensuring smooth operation.
To calculate the required thickness of the lubricant layer, the tangential velocity at the shaft's surface must first be determined. This velocity is calculated by converting the rotational speed to angular velocity...

02:01Plant Cells and Tissues
65.7K
Plant tissues are collections of similar cells performing related functions. Different plant tissues will have their own specialized roles and can be combined with other tissues to form organs such as flowers, fruit, stem, and leaves. Two major types of plant tissue include meristematic and permanent tissue.

81.7K
All the digits in a measurement, including the uncertain last digit, are called significant figures or significant digits. Note that zero may be a measured value; for example, if a scale that shows weight to the nearest pound reads “140,” then the 1 (hundreds), 4 (tens), and 0 (ones) are all significant (measured) values.
