Study summary

The investigators aim to evaluate how different timing of anti-VEGF intravitreous injections affect visual acuity (BCVA) in patients with diabetic macular edema who are undergoing cataract surgery; and to evaluate how different timing of anti-VEGF intravitreous affect OCT CSF thickness and total number of postoperative injections in patients with diabetic macular edema who are undergoing cataract surgery.

Read the detailed description

Cataract is very common in diabetic patients and can lead to significant vision loss and disability without medical intervention. Diabetic patients, particularly those with diabetic macular edema (DME), experience poorer visual outcomes after undergoing cataract surgery compared to non-diabetics. An increased risk in the development of post-operative cystoid macular edema and exacerbation of baseline DME is reported and this poses a significant challenge in managing concomitant DME and visually-significant cataracts.

Goals of the study are to evaluate how different timing of anti-VEGF intravitreous injections (before operation, intra-operation or after-operation) affect visual acuity (BCVA) in patients with persistent diabetic macular edema who are undergoing cataract surgery; and to evaluate how different timing of anti-VEGF intravitreous injections affect OCT CSF thickness and total number of postoperative injections in patients with diabetic macular edema who are undergoing cataract surgery.

What researchers measure

Primary outcomes

  1. Change in best-corrected visual acuity (BCVA)

    BCVA is a measurement of the best vision correction that can be achieved, such as glasses, as measured on the standard Snellen eye chart. For example, if uncorrected eyesight is 20/200, but patient can see 20/20 with glasses, the BCVA is 20/20.

    Time frame: 1 month, 3 months , 6 months and 12 months after cataract surgery

  2. Change in optical coherence tomography (OCT) central subfield (CSF) thickness

    Optical coherence tomography (OCT) is an important imaging modality in the evaluation and management of retinal diseases. Change in central subfield (CSF) thickness will be measured and recorded.

    Time frame: 24 hours post-operatively, 1 month, 3 months , 6 months and 12 months after cataract surgery

Secondary outcomes

  1. Total number of postoperative injections

    Total number of postoperative injections will be calculated

    Time frame: 12 months after cataract surgery

  2. percentage of patients with diabetic retinopathy progression

    patients with diabetic retinopathy progression will be calculated

    Time frame: 12 months after cataract surgery
