UBM indicators in anterior capsular contraction syndrome

The article presents the results of UBM studies of patients with anterior capsular contraction syndrome (CS). Purpose. Тo use the UBM method to study the state of the ciliary body (CB) and the capsular bag of the lens in patients with CS. Material and methods. The study included 42 patients with capsular CS. The UBM HI-scan ultrasound biomicroscope (Optikon, Italy) was used. Results. The reduction of the capsule bag of the lens was accompanied by a significant decrease in the diameter of the anterior capsulotomy opening, IOL decentration and its displacement towards the posterior pole of the eye, stretching or damage to the zonula ciliaris, and an increase in the CB thickness. In 2 cases, ruptures of the CB and its separation from the place of attachment to the radix iridis were recorded. Conclusion. UBM is an effective assessment method for CS, which allows us to study the state of the capsule bag of the lens and CB, evaluate the effectiveness of laser treatment and predict the risks associated with a high probability of complications. Key words: capsular contraction syndrome, anterior capsule, lens, laser, UBM, ciliary body.

Late Nontraumatic Anterior Dislocation of Intraocular Lens with Complete Capsular Phimosis in Retinitis Pigmentosa

Intraocular lens (IOL) dislocation is an unusual but serious complication after cataract surgery. We are here to report a rare case which is nontraumatic IOL dislocated and prolapsed into the anterior chamber in a retinitis pigmentosa (RP) patient. Zonular weakness and capsular contraction are considered to be the main contributing factors of IOL dislocation in RP patients. Patients at risk should be recognized and managed accordingly intraoperatively or postoperatively.

Understanding Ocular Visual Function Beyond the Sphere and Cylinder Using Multimodal Imaging

We have presented two interesting cases that demonstrate the use of multimodal imaging in refractive surgery cases. The first case demonstrates a simple capsular contraction causing immense problems of light spread in an otherwise normal trifocal implanted patient. The second is a case of a hidden and problematic refractive surgery that again complicated a trifocal lens surgery. We have made many advancements in understanding the eyes optical elements and must use this to our advantage to help our patients.
