Summary
This summary is machine-generated.

Managing cataracts alongside corneal diseases requires careful planning. A combined triple procedure with core vitrectomy offers a safer, single-stage solution for cataract and corneal transplantation, improving visual recovery.

Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Cataract Surgery

Background:

  • Corneal diseases often coexist with cataracts, necessitating integrated surgical management.
  • Sequential keratoplasty followed by cataract surgery has drawbacks like multiple procedures and slow recovery.
  • The standard triple procedure (keratoplasty, cataract extraction, IOL implantation) risks complications like vitreous pressure issues and hemorrhage.

Purpose of the Study:

  • To evaluate the efficacy and safety of a combined triple procedure incorporating core vitrectomy for managing concurrent corneal and cataract diseases.
  • To address challenges associated with the conventional triple procedure, particularly vitreous pressure control and intraocular lens (IOL) power calculation.

Main Methods:

  • A modified triple procedure involving combined core vitrectomy before corneal trephination was performed.

Related Experiment Videos

  • Vitrectomy was executed via a single sclerotomy to control intraocular pressure.
  • Methods for calculating IOL power in the context of post-keratoplasty eyes were reviewed and discussed.

    • Main Results:

    • Combined core vitrectomy effectively controlled vitreous pressure, enabling safer execution of subsequent keratoplasty and cataract surgery.
    • This approach mitigates risks associated with the open-sky technique, such as posterior capsule rupture and expulsive hemorrhage.
    • Accurate IOL power calculation remains a challenge due to unpredictable keratometry readings post-keratoplasty.

    Conclusions:

    • The combined triple procedure with core vitrectomy is a safe and effective strategy for managing eyes with combined corneal and cataract conditions.
    • This technique facilitates single-stage surgery, rapid visual rehabilitation, and reduces endothelial cell trauma.
    • Further research into optimizing IOL power calculation methods for these combined procedures is warranted.
