BACKGROUND: Intraocular lens (IOL) repositioning and IOL exchange are the main methods of surgical treatment of late in-the-bag IOL dislocation. AIM: To evaluate refraction, induced corneal astigmatism and IOL tilt after surgical treatment of late in-the-bag IOL dislocation by transscleral suture fixation and exchange to iris-claw IOL with retropupillary fixation. MATERIALS AND METHODS: 78 of patients with late in-the-bag IOL dislocation were included. Transscleral suture IOL fixation was performed in group I (38 eyes), exchange to iris-claw IOL was performed in group II (40 eyes). Refractometry, keratotopography and optical coherence tomography of anterior segment were performed before surgery, 1 week, 1, 3 and 6 months after surgery. RESULTS: The groups did not differ in subjective and objective refraction. But there was significant variability of data in the group I 3 and 6 months after surgery. There was no difference in corneal astigmatism in both groups during 3 months, but a significant increase was found in group II 6 months after surgery. There was no difference in IOL tilt between groups before surgery. Decrease of IOL tilt in 180 degrees plane was observed after 1 month in group II, while there was no difference in 90 degrees plane between groups. CONCLUSIONS: Both methods of late in-the-bag IOL dislocation treatment allow to receive good refractive result, but refraction is less predictable after trans-scleral suture IOL fixation. Surgically induced astigmatism is higher in IOL exchange group due to large sclerocorneal tunnel incision. Transscleral suture IOL fixation does not cause clinically significant IOL tilt.

Background. Cataract is often associated with primary glaucoma. Prostaglandin analogues use is considered to be a risk factor for pseudophakic cystoid macular edema. Purpose. To evaluate the effect of prostaglandin analogues and non-steroidal anti-inflammatory drops on the central retinal thickness and the incidence of pseudophakic cystoid macular edema after phacoemulsification with intraocular lens implantation in patients with primary open-angle glaucoma. Materials and methods. 91 patients were enrolled in the study. 22 patients (22 eyes) were included in the first main group and 22 patients (22 eyes) were included in the second main groups. All patients in main groups had glaucoma and used prostaglandin analogues. 47 patients (57 eyes) without glaucoma were included in the control group. All patients were treated with topical antibiotics and steroids after phacoemulsification. Patients in the main second and in the control groups also received non-steroidal anti-inflammatory drops. The retinal thickness was measured by optical coherence tomography 2 weeks, 2 months and 6 months after the operation. Results. After the operation, the foveal thickness in patients of the first and the second groups was increased, but it had returned to the preoperative level after 6 months in the first group and after 2 months in the second group. The retinal thickness in the fovea in the control group decreased after the surgery and it has been increasing gradually but did not achieve the preoperative value. Conclusion. Prostaglandin analogues use after phacoemulsification with intraocular lens implantation does not affect the incidence of pseudophakic cystoid macular edema. Prescribing non-steroidal anti-inflammatory drops after the surgery helps to achieve faster normalization of the central retinal thickness.
