Ophthalmic Drug Delivery Systems01:23

Ophthalmic Drug Delivery Systems

Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...
Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Area of Science:

  • Ophthalmology
  • Surgical Education
  • Medical Technology

Background:

  • Ophthalmic surgical training faces challenges due to limited opportunities.
  • Current training methods like wet labs have limitations in realism and consistency.

Purpose of the Study:

  • To review available training and assessment tools for phacoemulsification surgery.
  • To explore technological advancements in surgical skill development.

Main Methods:

  • Conducted Medline searches using keywords: phacoemulsification, training, curriculum, virtual reality, and assessment.
  • Manually reviewed reference lists of identified articles.

Main Results:

  • Virtual reality simulators offer psychomotor skill training and objective assessment for phacoemulsification.
  • Emerging tools include Objective Assessment of Skills in Intraocular Surgery (OASIS) and Global Rating Assessment of Skills in Intraocular Surgery (GRASIS).
  • Video-based assessments and dexterity analysis technology (e.g., ICSAD) reduce subjectivity and provide objective evaluation.

Conclusions:

  • Technological advancements are crucial for ophthalmology training and assessment.
  • Improved training and re-validation opportunities will enhance patient care.
