To investigate the intraocular pressure (IOP) and factors associated with greater IOP changes in patient who underwent cataract extraction (CE) with in-the-bag intraocular lens (IOL) implant.

All patient who underwent CE with IOL implant with a postoperative six-week follow-up in Lincolnshire United Hospitals NHS Trust from March 2022 to September 2022 were enrolled.

IOP was measured by Applanation Tonometry before and at two-month follow-up. Parameters such as age, sex, history of diabetes mellitus, history of tobacco smoking, ocular comorbidities, pre-operative IOP, axial length (AL), anterior chamber depth (ACD) and white-to white (WTW) and type of IOL implant were collected. Exclusion criteria were previous trabeculectomy; intraocular procedure during the follow-up period; diagnosis of primary or secondary angle closure or angle closure suspect; presence of other comorbidities affecting IOP. Factors associated with IOP changes were analyzed in univariable and multivariable analysis.

133 eyes of 119 patients were included. Mean age (±SD) was 75.68 (±9.02). 16/133 (12.0%) eyes had diagnosis of OAG, 4.5% had ocular hypertension. Mean preoperative IOP (SD) was 17.51 (±4.29). Mean AL (SD) was 23.49 (±1.79), mean ACD (SD) 2.9 (±0.48), 45.85% underwent CE with a single-piece in-the-bag hydrophilic IOL implant (Akreos©MI60), whereas 54% received hydrophobic (EyeCee One©) IOL implant. At the 2-month postoperative visit, mean IOP was significantly lower in the hydrophilic IOL group compared to the hydrophobic IOL group (-3.50mmHg vs. -1.14 mmHg, P=<0.001). Age, preoperative IOP, diagnosis of glaucoma and type of IOL were significantly associated with greater IOP changes.

Greater IOP reduction is associated with age, pre-operative IOP, diagnosis of glaucoma and material of IOL implant. There parameters might help predict IOP reduction after cataract extraction.
