Keratopigmentation (Corneal Tattoo) - Our First Experience.
Summary
Keratopigmentation, a cosmetic corneal tattoo, effectively improves the appearance of blind eyes with leucomas. This safe procedure using skin tattoo inks yielded satisfying results with no complications in four patients.
Area of Science:
- Ophthalmology
- Cosmetic Surgery
Background:
- Keratopigmentation offers a cosmetic solution for corneal leucomas and other pathological eye conditions.
- The procedure involves implanting pigments into the corneal stroma to enhance eye appearance.
- Traditional methods use skin tattoo inks, with newer biocompatible mineral pigments also available.
Observation:
- Four case reports detail patients with corneal leucomas seeking keratopigmentation for cosmetic improvement of blind eyes.
- Skin tattoo inks were utilized for the keratopigmentation procedure in these cases.
Findings:
- All four patients achieved highly satisfactory cosmetic outcomes post-keratopigmentation.
- Postoperative examinations revealed no pigment diffusion, fading, or color changes.
- No adverse reactions, including toxic or immune responses, were observed.
Implications:
- Keratopigmentation is considered a safe and straightforward surgical technique.
- The procedure is cost-effective, avoids hospitalization, and involves a short recovery period.
- This offers a viable cosmetic option for individuals with visually impaired eyes due to corneal conditions.

What is an Experiment?
17.6K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

Thomson's e/m Experiment
6.7K
In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...

Controls in Experiments
16.5K
When conducting an experiment, it is crucial to have control to reduce bias and accurately measure the dependent variables. It also marks the results more reliable. Controls are elements in an experiment that have the same characteristics as the treatment groups but are not affected by the independent variable. By sorting these data into control and experimental conditions, the relationship between the dependent and independent variables can be drawn. A randomized experiment always includes a...

Randomized Experiments

The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Crossover Experiments

Crossover experiments, also called the repeated-measurements design, is a study design in which all experimental units are exposed to all treatments in different periods. Crossover experiments are generally used in psychology, the pharmaceutical industry, agriculture, and medicine.
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
