Chief complaint
An 83-year-old female presented with gradually decreasing vision in OD since cataract surgery; positive history of falling and hitting head 3 weeks earlier.
History
Past ocular history: S/P pseudophakia OD 2 months, 1 week S/P 20/30 with chronic moderate severe dry eye OS 1998 with CME? and dry eye and decreased vision of 20/60, epithelial basement membrane dystrophy (EBMD), blepharitis, chronic open angle glaucoma (Xalatan and Alphagan P).
Past medical history: Diabetes for 15 years; hypertension, arthritis, Parkinson's disease.
Exam
|
Best corrected visual acuity: |
20/40 OD, 20/70 OS |
|
External: |
1+ diffuse injection OU |
|
Slit lamp: |
|
2+ inferior keratitis OU, EBMD OU, anterior chamber clear, IOL OD |
|
IOL decentration (with dilation): Had dislocated superiorly and nasally. If don't dilate, may not see dislocation.

|
IOPs (applanation tonometry): |
19mmHg OD, 23mmHg OS |
|
Dilated fundus exam (DFE): |
no obvious macular edema in OD; cup-to-disk ratio 0.7 OU |
Assessment:
Decentered IOL secondary to trauma versus capsular fibrosis syndrome OD.
Plan/Treatment
Refer back to surgeon for repositioning of subluxated IOL.
Follow-up:
- S/P IOL exchange, IOL in sulcus
- Temporarily discontinue Xalatan OD
- Best corrected visual acuity: 20/50 OD
- IOPs (applanation tonometry): 23mmHg OD, 20mmHg OS
- Placed on Restasis bid OU for dry eye treatment
2-month follow-up: Doing well; improved corneal signs; less staining.

Chief complaint

Past medical history: Unremarkable.

|
IOPs (applanation tonometry): |
22mmHg OD, 20mmHg OS |
|
Dilated fundus exam (DFE): |
flat macula |
Assessment:
Dislocated IOL with monocular diplopia and decreased vision OD.
Plan/Treatment
Referral to surgeon for IOL repositioning.
IOL Decentration
- Reported rates of decentration vary from 7 to 40 percent
- Most obvious symptoms
- Decreased vision
- Glare
- Ghost images
- Monocular diplopia
- Etiology
- Lens unable to withstand the pressure exerted after capsular bag shrinkage
- Hydrophobicity of lens prevents adherence to capsular bag
- Softness and flexibility of lens causes lens deformation
- Capsular capture
