    Postoperative intraocular pressure (IOP) elevations are common after eye surgery. Many patients experience delayed IOP rise, even with initially normal pressures, particularly after cataract extraction.

    Area of Science:

    • Ophthalmology
    • Surgical Science

    Background:

    • Intraocular pressure (IOP) management is critical post-eye surgery.
    • Understanding patterns of IOP elevation is essential for patient care.

    Purpose of the Study:

    • To investigate the incidence of acute postoperative IOP rise.
    • To analyze the relationship between initial and delayed IOP elevations after ocular surgery.

    Main Methods:

    • Evaluation of 86 eyes undergoing intraocular surgery.
    • Monitoring of initial and delayed postoperative IOP levels.
    • Categorization of procedures including penetrating keratoplasty and extracapsular cataract extraction (ECCE).

    Main Results:

    • 22.5% of penetrating keratoplasty and 32% of ECCE patients had initial IOP > 23 mm Hg.

  • Delayed IOP elevation occurred in 90% of penetrating keratoplasty and 46% of ECCE patients with initial rise.
  • Delayed IOP rise also occurred in 43% of penetrating keratoplasty and 32% of ECCE patients with normal initial IOP.

    • Conclusions:

    • Acute IOP elevation is a significant concern following ocular surgeries like penetrating keratoplasty and ECCE.
    • Delayed IOP increases are frequent, irrespective of initial postoperative IOP, especially after ECCE.
    • ECCE patients with late pressure rise resemble normal eyes on prolonged steroid therapy.
