The Predictability of Preoperative Pilocarpine-Induced Lens Shift on the Outcomes of Accommodating Intraocular Lenses Implanted in Senile Cataract Patients

الملخص EN

Purpose.

To evaluate the predictability of lens shift induced by pilocarpine ( L S P i l o ) on the outcomes of accommodating intraocular lens (Acc-IOL) implantation.

Methods.

Twenty-four eyes of 24 senile cataract patients who underwent phacoemulsification and Acc-IOL implantation were enrolled.

L S P i l o was evaluated with anterior segment optical coherence tomography (AS-OCT).

At 3 months postoperatively, the best corrected distance visual acuities (BCDVA), distance-corrected near visual acuities (DCNVA), and subjective and objective accommodations were measured.

IOL shifts under accommodation stimulus ( I O L S A c c ) were evaluated with AS-OCT.

Results.

The mean L S P i l o was 112.29 ± 30.72 µm.

L S P i l o was not associated with any preoperative parameters.

The mean I O L S A c c was 130.46 ± 42.71 µm.

The mean subjective and objective accommodation were 1.54 ± 0.39 D and 1.27 ± 0.41 D, respectively.

The mean postoperative BCDVA and DCNVA (log MAR value) were 0.22 ± 0.11 and 0.24 ± 0.12, respectively.

L S P i l o positively correlated with I O L S A c c ( r = 0.541 ; P = 0.006 ), subjective accommodation ( r = 0.412 ; P = 0.022 ), and objective accommodation ( r = 0.466 ; P = 0.045 ), respectively.

Conclusion.

L S P i l o is an independent preoperative parameter associated with the postoperative Acc-IOL mobility and pseudophakic accommodation.

It may offer valuable information for ophthalmologists in determining the suitable candidates for Acc-IOL implantation.
