| PURPOSE: |
|---|
| To investigate the pathogenesis and related influencing factors of intraocular lens deflection caused by atypical pouch coarctation syndrome in patients with high myopia cataract, in order to provide reference for clinical selection and postoperative management. |
| METHODS: |
|---|
| A detailed case analysis was performed on one patient with high myopia. The patient's vision decreased after cataract surgery in the left eye, and the intraocular lens was found to be deviated after examination. Preoperative conditions include: femtosecond laser-assisted cataract phacoemulsification removal + intraocular lens implantation + capsule tension ring implantation, using ZEISS 809M intraocular lens. Patients experience vision loss after surgery, and specialist examinations are performed to assess the eye condition. The patient's unaided visual acuity in the left eye was 0.5, the intraocular lens was displaced upward, and the axis was 30.53mm. |
| RESULTS: |
|---|
| After surgery, the patient's unaided visual acuity in the left eye was 1.0, and the intraocular lens position was positive. It was found that the degree of capsule mechanization was positively correlated with the length of the eye axis. ZEISS Model 809M intraocular lenses are hydrophilic acrylate materials with hydrophobic surface properties and thin crystals. High myopia and the material and design of intraocular lenses may be factors that cause skewness. |
| CONCLUSIONS: |
|---|
| Pouch coarctation syndrome is more common in patients with high myopic cataracts, and the increase in axial length is positively correlated with the degree of lens capsule shrinkage. When dealing with patients with high myopia, and the design should be carefully selected to avoid postoperative complications. |
