Summary
Extracapsular cataract extraction with posterior chamber intraocular lens (IOL) implantation in highly myopic eyes shows good visual outcomes for axial lengths up to 28 mm. Longer axial lengths over 28 mm correlated with less satisfactory visual prognosis.
Area of Science:
- Ophthalmology
- Retinal Science
Context:
- Cataract surgery in highly myopic eyes presents unique challenges.
- Understanding visual outcomes based on ocular axial length is crucial.
Purpose:
- To evaluate the visual results of extracapsular cataract extraction with posterior chamber intraocular lens (IOL) implantation in highly myopic eyes.
- To correlate visual prognosis with ocular axial length.
Summary:
- 36 highly myopic eyes underwent extracapsular cataract extraction with posterior chamber IOL implantation.
- Follow-up averaged 33 months (range 12-77 months).
- 95% of eyes with axial lengths of 26-28 mm achieved corrected visual acuity of 0.5 or better; eyes with axial lengths >28 mm had less favorable outcomes.
- No complications like retinal detachment, glaucoma, or corneal dystrophy were reported.
Impact:
- Provides evidence for the efficacy of cataract surgery in specific high myopia cases.
- Highlights the importance of ocular axial length in predicting visual outcomes after surgery.
- Suggests a potential threshold for axial length impacting surgical success in high myopia.
