Femtosecond Lenticule Extraction (FLEx) for Spherocylindrical Hyperopia Using New Profiles.
Journal of Refractive Surgery (Thorofare, N.J. : 1995)
|January 10, 2018
Summary
This study explored new lenticule profiles for hyperopic femtosecond lenticule extraction (FLEx), achieving good refractive outcomes for spherocylindrical hyperopia. The FLEx procedure demonstrated safety and efficacy, with most patients achieving their intended visual correction.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Laser Vision Correction
Background:
- Hyperopic correction remains a challenge in refractive surgery.
- Femtosecond lenticule extraction (FLEx) offers a potential alternative for hyperopic correction.
- Optimizing lenticule profiles is crucial for predictable outcomes.
Purpose of the Study:
- To evaluate novel lenticule profiles for femtosecond lenticule extraction (FLEx) in treating spherocylindrical hyperopia.
- To assess the efficacy and safety of a modified laser scan sequence for hyperopic FLEx.
Main Methods:
- Prospective study of 39 eyes from 22 patients with hyperopia.
- Utilized a modified laser scan sequence for FLEx with specific optical zone and lenticule thickness parameters.
- Mean patient age was 49 years, with treatment aimed at low myopia in 75% of eyes due to presbyopia.
Main Results:
- Mean preoperative spherical equivalent was +1.96 D, and postoperative was -0.40 D at 9 months.
- 70% of eyes achieved correction within ±0.50 D, and 89% within ±1.00 D of the target.
- No serious complications or loss of two or more lines of corrected distance visual acuity were reported.
Conclusions:
- Femtosecond lenticule extraction (FLEx) with new lenticule profiles provides effective treatment for spherocylindrical hyperopia.
- Refractive results are comparable to established hyperopic femtosecond laser-assisted LASIK outcomes.
- The FLEx procedure is safe and predictable for hyperopic correction.

Ribosome Profiling
4.2K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

Extraction: Effects of pH
1.4K
Consider a neutral form of an amine, B, with a partition coefficient, K, in a liquid mixture containing organic and aqueous phases. The pH of the aqueous phase affects the charge on acidic and basic solutes, and the charged form is usually more soluble in the aqueous phase. Suppose the conjugate acid form of the amine is soluble only in the aqueous phase while the base form is soluble in both phases. Then the distribution coefficient, D, can be given as the ratio of amine concentration in the...

Taping Over Different Ground Profiles
417
Taping over varying ground profiles requires careful adaptation to achieve accurate measurements. On smooth, level ground with minimal vegetation, the tape can rest directly on the ground. Here, the taping team, typically consisting of a head and a rear tapeman, coordinates their positions with clear communication. The rear tapeman holds the tape at the starting point and guides the head tapeman toward a range pole placed beyond the endpoint, using hand or voice signals to ensure alignment.On...

Extraction: Advanced Methods
1.2K
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Profile Leveling and Cross Sections
1.7K
Profile leveling and cross-sections are surveying methods used to determine and document terrain elevations for infrastructure projects such as highways, railroads, canals, and pipelines. These methods provide data for earthwork planning and alignment of proposed routes. Profile leveling involves measuring elevations along a fixed line to create a vertical terrain profile. A surveyor sets up a leveling instrument at the benchmark (BM) and records a backsight (BS) to determine the...

Extraction: Partition and Distribution Coefficients
5.0K
The distribution law or Nernst's distribution law is the law that governs the distribution of a solute between two immiscible solvents. This law, also known as the partition law, states that if a solute is added to the mixture of two immiscible solvents at a constant temperature, the solute is distributed between the two solvents in such a way that the ratio of solute concentrations in the solvents remains constant at equilibrium.
