Summary
A new phacoemulsification technique called RAPID (rotation, alignment, placement, impaling, devouring) effectively removes soft cataracts. This stepwise method ensures safe and efficient cataract removal without specialized equipment.
Area of Science:
- Ophthalmology
- Surgical Techniques
Background:
- Cataract surgery is a common procedure to restore vision.
- Soft cataracts present unique challenges for phacoemulsification.
- Existing techniques may require specialized equipment or high vacuum settings.
Purpose of the Study:
- To introduce and describe the RAPID (rotation, alignment, placement, impaling, devouring) technique.
- To evaluate the safety and efficacy of the RAPID technique for soft cataracts.
- To assess outcomes including complications and endothelial cell loss.
Main Methods:
- The RAPID technique involves stepwise nucleus rotation, tip alignment, placement, impaling, and emulsification.
- Performed on 54 eyes with soft cataracts using the Centurion/Infiniti Phacoemulsification system.
- Key outcome measures included cumulative dissipated energy (CDE), ultrasound time (UST), fluid usage, and endothelial cell loss.
Main Results:
- Successful phacoemulsification and IOL implantation in all 54 eyes with no intraoperative complications.
- Low cumulative dissipated energy (CDE) of 1.03±0.61 and short ultrasound time (UST) of 3.84±3.27 seconds.
- Mean endothelial cell loss was 7.05±2.65% at 3-month follow-up.
Conclusions:
- The RAPID technique is a safe and effective en masse, non-fragmentation method for purely soft cataracts.
- It does not require specialized instrumentation or high vacuum settings.
- The technique facilitates easy and fast emulsification while protecting the posterior capsule and corneal endothelium.

Atoms — and the protons, neutrons, and electrons that compose them — are extremely small. For example, a carbon atom weighs less than 2 × 10−23 g. When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit (amu). The amu was originally defined based on hydrogen, the lightest element, then later in terms of oxygen. Since 1961, it has been defined with regard to the most abundant isotope of carbon, atoms of which...

The identity of a substance is defined not only by the types of atoms or ions it contains but by the quantity of each type of atom or ion. For example, water, H2O, and hydrogen peroxide, H2O2, are alike in that their respective molecules are composed of hydrogen and oxygen atoms. However, because a hydrogen peroxide molecule contains two oxygen atoms, as opposed to the water molecule, which has only one, the two substances exhibit very different properties.

Mass and weight are often used interchangeably in everyday conversation. For example, medical records often show our weight in kilograms, but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of the Earth on an object. It depends on the distance from the center of the Earth. Weight dramatically varies if we leave the Earth's surface, unlike mass, which does not vary with location. On the Moon, for example, the...

Mass concreting refers to the process of placing large volumes of concrete, such as in gravity dams. The heat generated during the cement hydration process and differential cooling rates within the concrete mass can lead to a temperature gradient, which can result in thermal cracks in the concrete mass.
To reduce the risk of such cracking, the concrete mix may incorporate low-heat cement and pozzolans to reduce the temperature rise. Pre-cooled angular aggregates and water-reducing admixtures...

The number of protons in the nucleus of an atom is its atomic number (Z). This is the defining trait of an element. Its value determines the identity of the atom. For example, any atom that contains six protons is the element carbon and has the atomic number 6, regardless of how many neutrons or electrons it may have. A neutral atom must contain the same number of positive and negative charges, so the number of protons equals the number of electrons. This means that the atomic number also...
