Cataract Surgery with Ocular Surface Disease: What to Consider

Cataract surgery is a standard procedure aimed at improving vision by removing the eye’s clouded lens and replacing it with an artificial one. However, this surgery can present additional challenges for patients with ocular surface disease (OSD). OSD often coexists with cataracts, and understanding the intricacies involved is advisable for achieving optimal surgical outcomes. A comprehensive assessment prior to surgery is recommended to address these complexities and ensure optimal patient care.

Understanding Ocular Surface Disease (OSD)

Ocular surface disease encompasses a range of disorders affecting the eye’s surface, including dry eye syndrome, blepharitis, and meibomian gland dysfunction. Common symptoms may include irritation, redness, blurry vision, and a gritty sensation in the eyes. Risk factors for OSD include age, gender, hormonal changes, and previous eye surgeries.

Managing patients with OSD who are undergoing cataract surgery poses unique challenges. OSD can exacerbate post-surgical inflammation, affect healing, and impact the accuracy of intraocular lens (IOL) power calculations. Therefore, managing OSD before proceeding with a cataract surgery in Singapore is recommended to improve surgical outcomes and patient satisfaction.

Special Considerations for Cataract Surgery with Different Kinds of OSDs

Specific considerations must be considered when managing cataract surgery for patients with ocular surface diseases. These considerations may vary depending on the type of OSD, and understanding these aspects is advisable for ensuring optimal surgical outcomes. Here are some of the common OSDs and the special considerations required for each:

1. Herpetic Eye Disease

Herpetic eye disease, caused by the herpes simplex virus (HSV), can complicate cataract surgery. Patients with a history of HSV may experience flare-ups around the time of surgery. It is advisable to ensure the infection is managed with antiviral medications before and after the procedure. Perioperative antiviral coverage can help mitigate the risk of recurrence and ensure optimal recovery.

2. Keratoconus and Cataract Surgery

Keratoconus is a condition where the cornea becomes thin and cone-shaped, distorting vision. This may present specific challenges during cataract surgery, particularly in lens power calculations and achieving desired refractive outcomes. Specialised IOLs, such as toric lenses, can be helpful, but careful consideration is needed. In some cases, a corneal transplant may be necessary before or after the procedure to optimise visual results.

3. Glaucoma Co-management

Patients with both glaucoma and cataracts may require careful co-management. The interplay between these conditions can affect surgical decisions and outcomes. For example, cataract surgery can lower glaucoma patients’ intraocular pressure (IOP), which might reduce the need for glaucoma medications. However, precise IOP management is critical, and collaboration with a glaucoma specialist in Singapore is recommended to design the procedure for each patient.

4. Cataract Surgery Post-Keratoplasty

Performing cataract surgery in patients who have undergone corneal transplants (keratoplasty) typically requires special considerations. The primary concern is the risk of endothelial cell loss, which can compromise the graft. Surgeons are advised to employ methods that may help protect the cornea during the procedure and plan for visual rehabilitation. Postoperative care is also recommended to maintain the health of the transplanted cornea and achieve the best visual outcomes.

5. Traumatic Cataracts

Cataracts resulting from ocular trauma can be particularly complex. Trauma can lead to irregularities in the eye structure, making surgery more challenging. Surgeons are advised to adopt a realistic approach to surgical outcomes, as severely traumatised eyes may not achieve perfect vision. Preoperative planning and patient education may be recommended to set appropriate expectations and prepare for potential complications.

Consult a Cataract Specialist to Protect Your Vision

Patients considering cataract surgery, especially those with OSD or other eye conditions, are advised to consult a specialist to ensure a thorough evaluation and customised procedure. In Singapore, the expertise of cataract specialists can make a difference in managing complex cases. Early intervention and regular check-ups may be necessary for managing your eyesight and maintaining a high quality of life.
