[Cataract surgery in very long axial myopia]
Summary
High myopia with very long axial length is common in China. Intraocular lens (IOL) implantation outcomes vary, with poorer visual acuity linked to increasing axial length and fundus pathology.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Biometry
Context:
- Senile cataract surgery analysis
- Eyes with axial length ≥ 27.00 mm
- Prevalence in Chinese population
Purpose:
- Analyze incidence and refractive characteristics
- Evaluate operative results of intraocular lens (IOL) implantation
- Assess outcomes in eyes with extreme axial lengths
Summary:
- 81 eyes with axial length 27.00-34.71 mm studied
- IOL implantation in 39 eyes showed 82.1% achieved ≥ 10/20 corrected vision
- 42 eyes without IOL implantation had 42.9% ≥ 10/20 corrected vision, with average length 31.68 mm
Impact:
- Myopia with very long axial length is common in China
- Poor postoperative corrected visual acuity (PCVA) linked to fundus pathology and increasing axial length
- Negative power IOL may be necessary for extremely myopic eyes
