Summary
Trypan blue dye aids visualization during cataract surgery (phacoemulsification) in eyes with corneal opacities, improving surgical success and visual outcomes for selected patients.
Area of Science:
- Ophthalmology
- Surgical Techniques
Background:
- Cataract surgery with corneal opacities presents visualization challenges.
- Phacoemulsification and foldable lens implantation require clear visualization of the anterior capsule.
Purpose of the Study:
- To assess the effectiveness of trypan blue dye in enhancing visualization during phacoemulsification and foldable lens implantation.
- To evaluate visual outcomes in patients with cataracts and corneal opacities undergoing this procedure.
Main Methods:
- 11 patients with cataract and nebulomacular corneal opacities underwent trypan blue assisted phacoemulsification.
- Surgical steps and postoperative visual acuity were monitored at multiple intervals.
Main Results:
- Trypan blue improved anterior capsule visualization, enabling successful capsulorhexis in all cases.
- Phacoemulsification was successful in all but one eye; visual acuity improved significantly in most patients.
Conclusions:
- Trypan blue assisted phacoemulsification is a viable option for selected cataracts with corneal haze.
- This technique offers acceptable visual results for patients awaiting or unsuitable for penetrating keratoplasty.
