Intraocular lens replacement in pseudophakic bullous keratopathy

|January 1, 1985
Summary
This study treated pseudophakic bullous keratopathy (PBK) with corneal transplants and new intraocular lens (IOL) implants. The procedure resulted in clear corneas and improved vision for most patients after 3 years.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Ophthalmic Lens Implantation
Background:
- Pseudophakic bullous keratopathy (PBK) is a significant cause of visual impairment after cataract surgery.
- Management often involves corneal transplantation, but visual outcomes can be variable.
- Previous strategies did not consistently address the underlying intraocular lens (IOL) issues.
Purpose of the Study:
- To evaluate the efficacy of a combined surgical approach for PBK.
- To assess visual outcomes and graft survival after combined corneal transplant and IOL exchange.
- To report on the long-term stability and safety of this combined procedure.
Main Methods:
- Fifty-three patients with PBK underwent corneal transplantation.
- Original intraocular lenses (IOLs) were removed and replaced with sutured posterior chamber IOLs.
- Vitrectomy was performed in most cases.
Main Results:
- 88% of corneal transplants remained clear.
- 75% of patients achieved a visual acuity of 20/200 or better.
- Corneal clarity and visual acuity remained stable at an average 3-year follow-up.
Conclusions:
- Combined corneal transplantation with IOL removal and replacement is an effective treatment for PBK.
- This approach yields favorable visual outcomes and long-term graft survival.
- The procedure alleviates pain and restores stable vision in PBK patients.
