Abstract:
We describe a technique of irrigating and thereby rapidly and effectively clearing the cornea of relatively large amounts of surface contaminants that reduce surgical visibility and may contribute to endophthalmitis. This technique is referred to as "macrowash." If the technique is required, it is usually at the commencement of cataract surgery, immediately after placement of the surgical drape. The technique not only saves time, but also reduces the volume of irrigating solution required by the "microwash" technique, which is traditionally carried out by the scrub nurse/surgical assistant using a Rycroft cannula attached to a 15 mL container of irrigating solution.
Insights
A new macrowash technique rapidly clears corneal contaminants during cataract surgery. This method is more efficient than traditional microwash, saving time and reducing irrigation solution volume.
Area of Science:
- Ophthalmology
- Surgical Techniques
Background:
- Corneal surface contaminants can reduce surgical visibility.
- Contaminants may increase the risk of endophthalmitis.
- Current irrigation methods can be time-consuming.
Purpose of the Study:
- To introduce and describe the macrowash technique.
- To highlight the efficiency of macrowash in clearing corneal contaminants.
- To compare macrowash with the traditional microwash technique.
Main Methods:
- The macrowash technique involves irrigating the cornea to remove surface contaminants.
- This method is typically employed at the start of cataract surgery.
- It utilizes a specific irrigation approach distinct from microwash.
Main Results:
- Macrowash effectively clears significant amounts of corneal surface contaminants.
- The technique rapidly improves surgical visibility.
- Macrowash reduces the volume of irrigating solution needed compared to microwash.
Conclusions:
- Macrowash is an effective and efficient method for clearing corneal contaminants during cataract surgery.
- This technique offers advantages in time-saving and reduced fluid usage.
- Macrowash can potentially mitigate risks associated with contaminants, such as endophthalmitis.
