Care Plan for Cataract
The primary care plan for patients with cataracts involves surgical intervention when visual function no longer meets the patient's needs and surgery provides a reasonable likelihood of improvement. 1 Phacoemulsification with foldable intraocular lens (IOL) implantation is the preferred surgical method due to better visual outcomes and lower complication rates. 2
Assessment and Diagnosis
- Identify cataract characteristics (nuclear, cortical, posterior subcapsular) and their impact on visual function 1
- Document symptoms including:
- Blurred vision
- Glare sensitivity
- Poor contrast sensitivity
- Impact on daily activities (reading, driving)
- Functional limitations
Management Algorithm
1. Early/Mild Cataract Management
For patients with early cataracts or those not yet ready for surgery:
Refractive correction adjustments:
Environmental modifications:
- Improve lighting conditions
- In limited circumstances, pupil dilation may temporarily improve vision around small central cataracts (note: may worsen glare) 2
Risk factor management:
2. Surgical Intervention
Indications for Surgery 2:
- Visual function no longer meets patient's needs
- Clinically significant anisometropia due to cataract
- Lens opacity interfering with management of posterior segment pathology
- Lens-induced inflammation or glaucoma
- Lens-induced angle closure
Contraindications to Surgery 2:
- Tolerable refractive correction provides adequate vision
- Surgery not expected to improve visual function
- Patient cannot safely undergo surgery due to comorbidities
- Appropriate postoperative care cannot be arranged
- Informed consent cannot be obtained
Preoperative Evaluation 2:
- Complete ophthalmic examination
- Document symptoms, findings, and indications
- Obtain informed consent after discussing risks, benefits, and expected outcomes
- Review presurgical evaluation results with patient
- Counsel on postoperative refractive options
- Discuss elective refractive options (astigmatism management, specialty IOLs)
- Consider impact of ocular comorbidities
- Formulate surgical plan (anesthesia, approach, IOL selection)
- Assess patient's mental and physical status
- Create postoperative care plan
- Evaluate for concurrent blepharoptosis
- Address patient questions about surgery and costs
- Assess communication barriers
- Ensure patient commitment to postoperative care
3. Surgical Approach
Preferred method: Sutureless small-incision phacoemulsification with foldable IOL implantation 2, 1
- Produces better uncorrected distance visual acuity
- Lower rate of surgical complications
- Enables astigmatism management and specialty IOL implantation
- Performed on outpatient basis
Alternative methods (for resource-limited settings):
- Manual small-incision cataract extraction (MSICS)
- Extracapsular cataract extraction (ECCE) 2
4. Perioperative Medication Management
- Antiplatelet therapy: Can generally be continued during surgery 1
- Systemic α1-adrenergic antagonists (e.g., tamsulosin): May increase surgical complications; some ophthalmologists temporarily discontinue preoperatively 3
- Intraocular antibiotics: Moxifloxacin or cefuroxime delivered intraoperatively reduces endophthalmitis rates from 0.07% to 0.02% 3
5. Postoperative Care
- Appropriate follow-up schedule
- Visual rehabilitation
- Treatment of complications
- Management of dry eye
- Continuation of necessary medications 1
Important Considerations
- No proven pharmacological treatments: Currently, there are no medications proven to eliminate existing cataracts or retard progression 2, 1
- Future developments: Research on potential pharmacological treatments is ongoing, including lanosterol therapy which showed promise in animal studies 4, 5
- Refractive benefits: Beyond vision restoration, cataract surgery can reduce dependence on eyeglasses through advanced technology IOLs (multifocal, toric), though these may involve additional costs not covered by insurance 3
- Impact on quality of life: Cataract surgery is associated with lower rates of falls (>30%) and dementia (20%-30%) 3
Special Populations
- Congenital cataracts: Require early intervention to prevent amblyopia; genetic testing is recommended to identify underlying causes and guide multidisciplinary management 6
- Patients with diabetes: Require careful monitoring as they have increased risk of cataract formation 2
Pitfalls to Avoid
- Delaying referral for surgical evaluation when visual function impacts quality of life
- Overlooking systemic conditions that may increase surgical risk
- Failing to manage patient expectations regarding refractive outcomes
- Neglecting to counsel on risk factor modification (smoking cessation, UV protection)
- Assuming pharmacological treatments can effectively treat or prevent cataracts
