Summary
The Boston Type I Keratoprosthesis (BI-KPro) offers a standardized surgical option for high-risk keratoplasty patients, especially after previous corneal graft failures. Proper patient selection and informed consent are crucial for successful outcomes.
Area of Science:
- Ophthalmology
- Biomaterials Science
- Surgical Innovation
Background:
- Keratoprosthetics involve replacing human corneal tissue with artificial devices.
- The Boston Type I Keratoprosthesis (BI-KPro) is the most frequently used artificial cornea globally.
Purpose of the Study:
- To demonstrate the surgical technique for Boston Type I Keratoprosthesis (BI-KPro) implantation.
- To provide an overview of indications, patient management, and outcomes for BI-KPro surgery.
Main Methods:
- Detailed surgical technique video of BI-KPro implantation.
- Review of 31 BI-KPro implantations, including indications, anesthesia, postoperative care, and complications.
Main Results:
- BI-KPro is indicated for high-risk keratoplasty, particularly in cases of repeated graft failure.
- Thorough patient evaluation, informed consent, and clear communication of prognosis and risks are essential for positive results.
Conclusions:
- The BI-KPro is an established, standardized treatment for high-risk corneal replacement.
- Preoperative patient education regarding prognosis, complications, and lifelong follow-up is vital for successful BI-KPro outcomes.

Overview
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

Hormones can be classified into three main types based on their chemical structures: steroids, peptides, and amines. Their actions are mediated by the specific receptors they bind to on target cells.

01:46Types of Selection
45.0K
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

01:09Types of Skewness
18.3K
If the frequency distribution of a data set is more inclined towards smaller or larger values, the distribution is said to be skewed. If data values are skewed to the right, then the distribution is called positively skewed. Conversely, if the plot is skewed to the left, the distribution is called negatively skewed.
For instance, in the middle of a pandemic, the geographical distribution of vaccine coverage may be positively skewed towards populations in the global north countries. However,...

01:20Types of Damping
7.7K
If the amount of damping in a system is gradually increased, the period and frequency start to become affected because damping opposes, and hence slows, the back and forth motion (the net force is smaller in both directions). If there is a very large amount of damping, the system does not even oscillate; instead, it slowly moves toward equilibrium. In brief, an overdamped system moves slowly towards equilibrium, whereas an underdamped system moves quickly to equilibrium but will oscillate about...

01:28Types Of Superconductors
1.6K
A superconductor is a substance that offers zero resistance to the electric current when it drops below a critical temperature. Zero resistance is not the only interesting phenomenon as materials reach their transition temperatures. A second effect is the exclusion of magnetic fields. This is known as the Meissner effect. A light, permanent magnet placed over a superconducting sample will levitate in a stable position above the superconductor. High-speed trains that levitate on strong...
