Summary
Manual blade superficial keratectomy is a safe and effective procedure for various corneal conditions, significantly improving vision and reducing astigmatism. While generally successful, some cases of recurrent corneal erosion may require further treatment.
Area of Science:
- Ophthalmology
- Corneal Surgery
Background:
- Superficial keratectomy is a surgical procedure to treat various corneal conditions.
- Understanding the indications and outcomes is crucial for patient management.
Purpose of the Study:
- To evaluate the indications and outcomes of manual blade superficial keratectomy.
- Assess changes in visual acuity and astigmatism post-procedure.
Main Methods:
- Retrospective review of 121 patients (156 eyes) from 2012-2017.
- Analysis of pre- and post-operative best-corrected visual acuity (BCVA) and corneal cylinder.
- Inclusion of patient demographics, surgical indications, and complications.
Main Results:
- Significant improvements in BCVA and astigmatism were observed in eyes with epithelial basement membrane dystrophy.
- Recurrence of symptoms occurred in 24% of eyes with recurrent corneal erosions.
- Complete epithelial healing was achieved in all eyes with no intraoperative complications.
Conclusions:
- Manual blade superficial keratectomy is a simple, safe procedure for diverse ocular surface pathologies.
- The procedure effectively improves visual acuity and reduces corneal astigmatism.
- It offers symptomatic relief for patients with specific corneal conditions.

Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenolphthalein is a colorless substance in any aqueous solution with a hydronium ion concentration greater than 5.0 × 10−9 M (pH < 8.3). In more basic solutions where the hydronium ion concentration is less than 5.0 × 10−9 M (pH > 8.3), it is red or pink. Substances such as phenolphthalein, which can be used to determine the pH of a solution, are...

02:24Predicting Reaction Outcomes
10.8K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...

2.8K
Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...

1.8K
Respiratory assessment is a cornerstone of nursing assessments, crucial for the early detection of patient deterioration. This evaluation transcends routine procedures, representing a critical skill nurses must master to ensure optimal patient care.
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...
