Cataract, Lens Implantation, Intraocular
Conditions
Brief summary
The goal of this observational study is to evaluate whether different intraocular lens (IOL) injectors affect surgical outcomes in patients aged 40 and older undergoing cataract surgery. The main questions it aims to answer are: * Do different IOL injectors change the size of the corneal incision during surgery? * Do the injectors lead to different rates of complications during or after surgery? Researchers will compare the use of three different IOL injectors: two preloaded models (pioli™ and pioli™ Plus) and one manually loaded model (lioli™), to see if the preloaded systems improve surgical results compared to the manual one. Participants will: * Undergo routine cataract surgery using one of the three injectors, randomly assigned. * Have measurements taken before and after surgery (e.g., vision tests, corneal incision size). * Be monitored for any side effects or complications during and after the procedure.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Corneal Incision Size | Day of surgery (intraoperative) | Measurement of the corneal incision before and after intraocular lens (IOL) insertion using each type of injector. Difference in incision size (in mm) |
| Incidence of Adverse Events | From surgical incision to end of surgery, assessed up to 120 minutes (intraoperative), and From end of surgery until postoperative day 30 (postoperative) | Number and type of ocular and non-ocular adverse events (serious and non-serious) recorded from initiation of the intra-ocular lens (IOL) implantation, both intraoperative and early postoperative period (up to 30 days). Percentage of participants with any AE |
