Summary
This study presents a modified ab externo technique for sulcus intraocular lens (IOL) implantation in dogs. The approach demonstrated a high success rate with outcomes comparable to existing methods for lens instability.
Area of Science:
- Veterinary Ophthalmology
- Surgical Techniques
Background:
- Lens instability and luxation are significant challenges in veterinary ophthalmology.
- Intraocular lens (IOL) implantation is a common solution for these conditions.
Purpose of the Study:
- To describe a modified ab externo surgical method for sulcus IOL fixation.
- To evaluate the outcomes and complications associated with this novel technique.
Main Methods:
- Retrospective review of patient records from January 2004 to December 2020.
- Analysis of cases involving lensectomy and sulcus IOL implantation using the modified ab externo approach.
- Assessment of post-operative complications and visual outcomes.
Main Results:
- Nineteen canine eyes underwent the modified ab externo sulcus IOL implantation.
- A visual outcome was achieved in 89.5% of eyes at the final follow-up.
- Complications included posterior ocular hypertension (POH) in 42.1% and glaucoma in 31.6% of eyes.
Conclusions:
- The modified ab externo technique offers a potentially less technically demanding option for sulcus IOL implantation.
- Success rates and complication profiles are comparable to previously reported methods.
- This technique provides a viable surgical option for managing lens instability in dogs.
