Summary
This study compared trephine use for cataract surgery sections to traditional keratome and scissors methods. Trephine use minimized complications and reduced astigmatism, improving surgical outcomes.
Area of Science:
- Ophthalmology
- Surgical Techniques
Background:
- Cataract surgery involves creating sections for lens removal.
- Traditional methods like keratomes and scissors have limitations.
Purpose of the Study:
- To evaluate the efficacy of using a trephine for lamellar cataract sections.
- To compare trephine use against keratome and scissors methods.
- To assess complication rates and visual outcomes.
Main Methods:
- 100 cases of senile cataract keratoplasty.
- Lamellar cataract sections created using a trephine (3 to 9 o'clock position).
- Comparison with sections made by keratome and scissors.
Main Results:
- Trephine use reduced complications related to wound healing.
- 41% of cases experienced no astigmatism post-surgery.
- Ab externo sections facilitated the insertion of preplaced sutures.
Conclusions:
- Trephine use offers advantages in cataract keratoplasty.
- Improved wound healing and reduced astigmatism are key benefits.
- Facilitates efficient suture placement for better surgical outcomes.
